A researcher observes the weight of a class of 36 students in high school. The given table shows the data she collected (in kg). 71 70 67 68 75 69 70 72 74 71 77 67 68 72 74 70 72 71 75 69 68 71 70 72 A. The researcher's null hypothesis is Ho: μ = 70 and the alternative hypothesis is HA: μ‡ 70. B. The researcher's null hypothesis is Ho: μ ≥70 and the alternative hypothesis is HA: μ ≤70. C. The researcher's null hypothesis is Ho: μ ≥70 and the alternative hypothesis is HA: μ‡ 70. D. The researcher's null hypothesis is Ho: μ = 70 and the alternative hypothesis is HA: μ ≥70. 72 67 71 74 73 72 The researcher wants to test whether the mean weight of all high school students in the state (u) would be 70 kg or not. So, the null and the alternative hypotheses for the test the researcher wants to conduct are: For a prespecified 5% significance level, the p-value of the test the researcher wants to conduct is (Round your answer to four decimal places.) 69 67 74 72 73 71 A researcher observes the weight of a class of 36 students in high school.
