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 68 68 72 72 67 74 72 68 71 75 77 69 67 22222E 75 70 71 71 67 67 68 71 74 70 71 71 72 72 70 73 73 71 71 72 71 The researcher wants to test whether the mean weight of all high school students in the state () would be 70 kg or not. So, the null and the alternative hypotheses for the test the researcher wants to conduct are: OA. The researcher's null hypothesis is Ho: OB. The researcher's null hypothesis is Ho: OC. The researcher's null hypothesis is Ho: OD. The researcher's null hypothesis is Ho: 70 and the alternative hypothesis is HA: 70. 270 and the alterative hypothesis is HA: 70. 70 and the alternative hypothesis is HA: 270. 270 and the alternative hypothesis is HA: 70. 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.) The calculated p-value suggests that we will the null hypothesis
