H0: π ≤ 0.5
2) What is the alternative hypothesis (H1)?
H1: π > 0.5
3) Sample statistic:
a. What is the meaning of the sample statistic?
A sample statistic is calculated numerical value that characterizes some aspect of sample set of data, often meant to estimate the real value of the corresponding parameter in an underlying population.
What is its value?
0.05
4) Test statistic:
a. What is the meaning of the test statistic?
The test stat is the distance of the sample proportion from the population proportion in standard errors of the distribution of the test statistic
b. What is its value?
0.8944
5) Critical values:
a. What is the meaning of critical value?
Critical value(s) is a factor used to compute the margin of error. Critical value(s) of the test statistic bounds the rejection region(s) of probability alpha = the risk we are willing to take of rejecting H0 when H0 is true

b. What is (are) the critical value(s)?
Critical lower value is 1.6449 ...Download file to see next pagesRead More

Represented as ? = 1.73 Ha: New toothpaste lessens cavities in comparison to other brands, indicated as ? < 1.73 c) we cannot apply the z-test or the t-test since we require the standard deviation apart from the mean alone of the new brand toothpaste. Sample size=60, sample mean = 1.5 d) Population standard deviation or sample standard deviation – missing hypothesisized mean = 1.73 e) Ho will be rejected since t-test is not applicable f) lack of standard deviation makes determination of 95% confidence interval impossible since it requires sample mean +/- t critical value*s/sqrt n 4.
