Question: Options for blanks with arrows, The sample (is or is not) random and the observations (are or are not) independent. The distribution of the heights

Options for blanks with arrows, The sample (is or is not) random and the observations (are or are not) independent. The distribution of the heights is (not normally distributed, right skewed, left skewed, or normally distributed) Since the p value is (less than or equal to or greater than) the significance level, (reject or do not reject) Ho. There is (insufficient or sufficient) evidence to...

In Country A, the population mean height for 10-year-old girls is 55.4 inches with a standard deviation of 2.4 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 54.6 inches with a standard deviation of 2.6 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 O B. Ho: H = 55.4 O C. Ho: H = 55.4 Ha: H = 55.4 Ha: H 55.4 O D. Ho: H = 55.4 O E. Ho: H # 55.4 OF. HO: H
