Asearcher observes the weight of a ciass of 36 students in high school. The given table shows the data she collected in kaO 70 68 70 68 75 70 69 73 72 69 67 67 67 74 72 68 71 74 68 71 70 71 74 72 75 77 66 70 73 73 69 67 71 72 72 71 The researcher wants to test whether the mean weight of all high school students in e state () would be 70 kg or not. So, the null and the altemative hypotheses for the lest the researcher wants to conduct are OA The researchers nul hypothesis is H =70 and the alternative hypothesie is H70. OB. The researcher's nul hypothesis is Hg = 70 and the altemative hypothesis is Ha270. OC. The researcher's null hypothesis is Hyi p270 and the alternative hypothesis is HS70. DD. The researcher's nul hypothesis is Hi2 70 and the altermative hypothesis is H70. or a prespecified 5% significance level, the p-value of the test the researcher wants to conduct isD Round your answer to four decimal places) the null hypothesis he calculated p-value suggests that we will
