Question

You want to create a simulation of the following scenario. The popalation of school A is made up of29% 9th graders, 25% 10th graders, 25% í lth mders, and 25% į2th graders The populatenof school B is made up of 40% 9th grader, 30% 100 ฮader, 20% 11th pader and 10% 12th graders (1 poie) What is the best way to assign values for a simulation ing a random digits table? School A: 9th grade is repeesensted with 0.10th grade is represented withs 1. 11th grade is represented with 2. 12th grade is represented with 3.

You record the nuember of sunmy days out of a sample of 90 randomly-selected days in City A ( pott) and City B. In City A's sample, there were 54 sunny days. In Caty B's sample, there were 63 sunmy days Is City B significantly sunnier than City A7 Use a significance level of o os z approxmately equals 2.00 for a P-value of 0.02275. Since the P-value is less than 0.05, fail to reject the mull hypothesis that there is no difference in the commute times z approximately equals 1.41 for a P-value of 0.078652 Since the Pavalue is greater than 0.05, fail to reject the null bypothesis that there is no difference in the commute tizes z approximately equals 1.41 for a P-value of 0 039326 Since the P-value is less than 0 05, reject the null hypothesis that there is no difference in the commute times O z approximately equals 2.00 for a P-value of O 02275 Since the Pvalue is less than 0.05, reject the null hypothesis that there is no dafference in the commute times

Answer 1

as we can ses that the obtained p-value is greater than 0.05(given significance level)

So we fail to reject the null hypothesis

Option 2 is correct.
