3. ________ In a two-sided hypothesis test, the observed test statistic is determined to be Z = -2.5. The p-value for this test is (A) 0.1091 (B) 0.0538 (C) 0.0062 (D) 0.0124 Can you explain your answer? thank you
Consider a significance test for a null hypothesis versus a two-sided alternative. State all values of a standard normal test statistic z that will give a result significant at the 10% level but not at the 5% level of significance.
section 9.4 Suppose the mean height of women age 20 years or older in a certain country is 62.5 inches. One hundred randomly selected women in a certain city had a mean height of 61.0 inches. At the 1% significance level, do the data provide sufficient evidence to conclude that the mean height of women in the city differs from the national mean? Assume that the population standard deviation of the heights of women in the city is 4.1 inches...
