a. Using the critical value approach test the claim that the salaries from both universities are equal. Includeall key steps of the test. b. Use the four-step P-value approach and test the claim that the salaries from both universities are equal.c. Are the conditions met for using this test? A study was conducted to determine if the salaries of the professors from two neighbouring universities wereequal. A sample of 20 professors from each university was randomly selected. The mean from the first universitywas $109,100 with a population standard deviation of $2300. The mean from the second university was $110,500with a population standard deviation of $2100. Assume that the distribution of professor salaries, at bothuniversities, are approximately normally distributed. Level of significance = 0.05.

Let be the population mean salaries of the professors from two universities.Given that,

find p value and its meaning please A survey of 1000 adults from a certain region asked, "If purchasing a used car made certain upgrades or features more affordable, what would be your preferred luxury upgrade?" The results indicated that 58% of the females and 51% of the males answered window tinting. The sample sizes of males and females were not provided. Suppose that of 600 females, 348 reported window tinting as their preferred luxury upgrade of choice, while of 400 males, 204 reported window tinting as their preferred luxury upgrade of choice. Complete parts (a) through (d) below. a. Is there evidence of a difference between males and females in the proportion who said they prefer window tinting as a luxury upgrade at the 0.05 level of significance? State the null and alternative hypotheses, where π1 is the population proportion of females who said they prefer window tinting as a luxury upgrade and π2 is the population proportion of males who said…

Twenty years ago, 52% of parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. A recent survey found that 281 of 800 parents of children in high school felt it was a serious problem that high school students were not being taught enough math and science. Do parents feel differently today than they did twenty years ago? Use the a=0.1 level of significance. *** Because npo (1-Po) = 199.7 less than 5% of the population size, and the sample can be reasonably assumed to be random, the 10, the sample size is requirements for testing the hypothesis are satisfied.
