Determine the regression equation for the data. Round the **final** values to three significant digits, if necessary.
= -2.79 + 0.950x
= -2.79 + 0.897x
= -3.79 + 0.801x
= -3.79 + 0.897x
Compute the coefficient of determination. Round your answer to four decimal places.
A regression equation is obtained for a set of data points. It is found that the total sum of squares is 103.5, the regression sum of squares is 89.8, and the error sum of squares is 13.7.

d. Then,
P(B|T) = [(42/100)(42/83)]/ (42/83)
= 42/100
= 0.42
e. The events B and T are independent because the chances of B to occur do not affect the chances of T to occur and vice versa. In other words, the probability of event B given event T is the probability of event B. Then the probability of event T given event B is the probability of event T. **Finally**, the third rule applies in which the probability of event B and T is equal to the product of probability of event B and probability of event T.

... Question We firs set the null and the alternative hypotheses. The null hypothesis will be de d by (H0) and the alternative hypothesis as (H1)
(H0): μ = 125
(H1): μ ≠ 125
We now calculate the test statistic in order to be able to test the above hypothesis and decide on whether or not to reject or accept the hypothesis. The sample mean is give by $129.50, the sample size is 47 and the sample standard deviation is $18 and that α = 0.10
Z = {Sample mean- μ0}/ δ/√n = {129.50-125} ÷ 18/√47 = 1.714. Since we have a positive value of Z, we will need to pull all the values of α on the right of the mean of the data. Hence we obtain the following results. The value... Question We...

INTRODUCTION
In this study, I have researched on the rise of Diabetes, which is at an alarming rate, compared to other chronic diseases in the UK. I will add a global context to my study. The rise in Diabetes does not prevail only in the UK but also other countries mostly developing nations. Also I have added to my research that if Diabetes is taken care off, then many patients could be saved from severe complications like loss of vision, high blood pressure, elevated cholesterol levels and kidney failure.
The aim of this study is to investigate how patients with Diabetes... Report confirming that Diabetes, compared...

...**Stat** big **project** **Stat** big **project** The topic that we are doing is life expectancy and how factors such as HIV, access to clean water, and many others affect how long a person is expected to live. According to the World Bank, it seems that life expectancy greatly varies when we compare poor, third world countries such as many of the countries within Africa to rich, developed countries like the United States and the United Kingdom. This is due to the citizens of developed countries, such as the United Kingdom and the United States, having access to hygiene and other basic human necessities of life, like food, clean water, and shelter. The relationship between having...

...April 27, Business statistics **project** Statistical analysis is important to managerial decisions as it offersinsights into data. Its results include summaries of trends and analysis of possible differences in variables and their significance for informed decisions. This discussion offers analysis of data on age, household income, and years of education of customers for five major motor vehicle companies in North America. The discussion is based on the hypothesis that Cadillac has retained control of the segment of older men and has lost the other segment to its competitors and that this is a possible factor to decline in the company’s market control.

1. Introduction
Gross domestic product has always been considered as one of the most important indicator to represent the performance of the economy. The economic performance can always be represented in terms of the production level within the economy. The gross domestic product is an aggregate measure of production that can be represented as the sum of values or products produced by the residents of the country. It does not include the products or the subsidies, which are not considered part of the value of their output. The GDP refers... impact of exports...
