Two groups of students are given a problem-solving test, and the results are compared. Group 1 Group 2 x with bar on top1 = 83.6 top enclose x 2 end enclose= 79.2 s1=4.1 s2=3.9 n1=36 n2=36 At α= 0.01, can it conclude that there is a significan difference in means of two groups? Explain with the 5 steps of hypothesis-testing.

A foreign car manufacturer advertises that its newest model, the Bullet, rarely stops at gas stations. In fact, they claimed that its EPA rating for highway driving is at least 32.5 mpg. However, the results of a recent independent study determined the mpg for 50 identical models of the Bullet, with these results: n = 50, x= 30.4 mpg, and s = 5.3 mpg.This report failed to offer any conclusion, and you have been asked to interpret these results by someone who has always felt that the 32.5 figure is too high. What would be your conclusion using a significance level of 5%?Z = 1.645
A medical researcher says that less than 74%of adults in a certain country think that healthy children should be required to be vaccinated. In a random sample of 600adults in that country, 71% think that healthy children should be required to be vaccinated. At α=0.01, is there enough evidence to support the researcher's claim? Complete parts (a) through (e) below. (a) Identify the claim and state H0 andHa. Identify the claim in this scenario.

Hello, Can you please help me solve this on my ti 84? Thank you. ex 4)You wish to test the following claim (HaHa) at a significance level of α=0.002α=0.002. Ho:p1=p2Ho:p1=p2 Ha:p1>p2Ha:p1>p2You obtain 165 successes in a sample of size n1=656n1=656 from the first population. You obtain 122 successes in a sample of size n2=588n2=588 from the second population. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial distribution.What is the test statistic for this sample?
