Download file to see previous pages To compute the total scores for the algebra test from the item scores, we use the ‘compute function’ by going to the transform menu at the top of the data view screen then selecting ‘compute’. On the dialog box that pops up, we type total in the window labeled target variable and type sum(item1 to item 8) in the window labeled Numeric Expression. Clicking on the Ok button gives us the totals which are 8, 6, 5, 7, 4, and 6.  From the two tables;a) Mean algebra score is 6b) T-test Value is 6.928c) P-value is 0.001  for the 2-tailed test and 0.0005 in the case of a one tailed test4. Result Section based on the AnalysisA one sample T-test was conducted on the total scores for algebra from the item scores to establish whether the Involvement Technique is effective in teaching algebra by evaluating whether the means were significantly different from 2. Since the one-tailed probability is considerably less than 0.05, we fail to accept the null hypothesis and conclude that that the method is effective in teaching algebra to first graders. Provided below is the histogram with the normal curve for the distribution of the totals.  To compute scores to obtain a total index of Life Stress (ILS) at age 40 & 60), we use the ‘compute function’ by going to the transform menu at the top of the data view screen then selecting ‘compute’. On the dialog box that pops up, we type total in the window labeled target variable and type sum all the items in the window labeled Numeric Expression. ...Download file to see next pagesRead More

...rate will not increase, and the bonds of the country will be significantly appealing (LATHAM & PROWLE, 2012). Lorraine: I agree with you that my approach has some drawbacks. However, the drawbacks of your approach are much more serious. Your approach will not solve the problem of employment; rather, it will cause more unemployment. b. Large Debt and Deficit Lorraine: The Keynesian approach is best suited to reduce large debt and deficit. Since the government has instigated spending in the economy, it is projected that income will increase. Additionally, instigating expenditure will attract investors, thus increasing income. This increase in income will be used to reduce the deficit after the recession. This is hinged on...

T-test and Correlation

...T-test and Correlation This paper will analyze difference in the percentage usage of prepositions in writing between native and non native speaker ofEnglish in their texts. For this, 10 texts written by a native speaker of English and another 10 texts written by a non-native speaker of English (Arab writer) in the usage (percentage) of prepositions were collected (table 1). The research hypothesis is “Is there a difference in the use of prepositions in writing between native and non native speaker of English?” The null and alternate hypotheses are H0:µnative = µnon-native H1:µnative ≠ µnon-native The selected level of significance, α is 0.05. The test selected is...

Econ 157 Problem Set

...Full Question A False. The Kuznets hypothesis s that the income inequality in poor countries first increase at a decreasing rate, then reaches a maximum and decline at an increasing rate with respect to per-capita income. Kuznets curve is inverted U shape. Its x and y axis shows per-capita income and inequality respectively. Therefore the slope of the curve denotes the growth rate of inequality at low per-capita income levels and the rate of declining of inequality at high per-capita income levels. 2. Question A-1: True. By drawing Lorenz Curves of two countries in the same panel the income inequality of those countries can be compared. These curves can cross in more than one place. Here an unequivocal statement...

...to get involved in high risk pools that are expensive and ineffective. An individual with this cover will never have to entirely forego the health cover and services that are so much needed. It is because of this reason that experts explain that not all pre-existing conditions are serious such as is the case with cancer, diabetes or kidney complications. They also believe that the purchase of this cover will help patients obtain medical services in less expensive ways hence a stress-reduced medical process. Moreover, they will be assured of the services whenever they require them. 2. The pluralist approach to policy making differs from the policy analysis approach of class and elites in the sense that the former does not...

...PROBLEM SET of Chapter 2 Question 5 pg 57 Chapter 5 Q18 pg 190 In the case of this sentence, and in relationshipto the Grice’s Maxim’s, there was a combined lack of maxim of maxim of relation and maxim of manner. It is just strange and a bit humorous that a question requiring explanation for the presence of the biscuits to be answered by ‘they are just lying there’. This is a form of ambiguity and unnecessary prolixity. Such an answer was irrelevant, lacked order and was ludicrous. The humour comes to the idea of the biscuits being in the wrong place without explanation. The second issue is equally far from the expected. By co-operative principle, this answer was not informative and was clearly out of...

The measurement of a flow is after everyone year, which represents the total value of transactions during an accounting period and so is gross domestic product. Q2) Various components will affect the gross domestic product. Examples of such include; payment of tuition as it will add on the GDP as payment for a service. Payment of a teen to mow lawn will also affect the GDP, as it is a service offered. Spending of the pharmaceutical companies in search of Ebola vaccine will also add affect the GDP, as it is a new service offered hence will contribute to the GDP. The government hiring more police officers will bring a new service in the industry... Topic: MACRO...

...expenditures. We performed a t-test for equality of means, we observe the p-value to be 0.046 (a value less than α=0.05), this leads us in rejecting the null hypothesis of equal mean between the expenditure on radio and that on the newspapers. Conclusion Based on the results shown above, it is evident that more money was spent on newspaper advertisements than was spent on radio advertisements. Since we rejected the null hypothesis, we conclude that indeed the expenditure made on radios was significantly different from that made on newspapers. Part 2: Simple Regression Analysis Based on a thorough analysis of the data provided do you...
