A research report claims that mice with an average life span of 32 months will live to be about 42 months old when 40% of the calories in their diet are replaced by vitamins and protein. Is there any reason to believe that p 42 OB. Ho: H = 42 OC. Ho: H #42 Hy: H = 42 Hy : H1 = 42 Hy: 1 = 12 O D. Ho: H = 42 VE. HO H = 12 OF HO H = 42 Hy : H # 42 Hy : H = 42 He: 14 > 42 Find the test statistic. (Round to two decimal places as needed.) A random sample of 66 bags of white cheddar popcorn weighed, on average, 5.75 ounces with a standard deviation of 0.22 ounce. Test the hypothesis that u = 5.8 ounces against the alternative hypothesis, u O C. (>
