Question b is cut off these are the question Determine the null and alternative hypothesesOptions are the same as the options for question A-Find the test statistic, t =-Find the p value, p value = Interpret the results of the test Since the p value is (less than or equal to, greater than) the significance level, (reject or do not reject) H0. There is (sufficient or insufficient) evidence to conclude that the height for 10 year old girls from Country B is significantly different from Country A population mean at a significance level of 0.05- Explain why the t values and p values for part a and b are different a. A larger n causes a larger SE (wider sampling distribution) with more area in the tails, as shown by larger p value b. A larger n causes a smaller SE (narrower sampling distribution) with less area in the tails, as shown by larger p value c. A larger n causes a larger SE (wider sampling distribution) with less area in the tails, as shown by smaller p value b. A larger n causes a smaller SE (narrower sampling distribution) with less area in the tails, as shown by smaller p value

In Country A, the population mean height for 10-year-old girls is 55.4 inches with a standard deviation of 2.3 inches. Suppose a random sample of 15 10-year-old girls from Country B is taken and that these girls had a sample mean height of 55 inches with a standard deviation of 2.7 inches. Assume that heights are Normally distributed. Complete parts (a) through (c) below. a. Determine whether the population mean for height for 10-year-old girls from Country B is significantly different from the Country A population mean. Use a significance level of 0.05. Determine the null and alternative hypotheses. Choose the correct answer below. O A. Ho: H 55.4 Ha: H = 55.4 O D. Ho: H > 55.4 O E. Ho: H = 55.4 OF. Ho: H = 55.4 Ha: H = 55.4 Ha: H # 55.4 Ha: H
