An education researcher claims that at most 8% of working college students are employed as teachers or teaching assistants. In a random sample of 300 working college​ students, 9​% are employed as teachers or teaching assistants. At alphaαequals=0.05, is there enough evidence to reject the​ researcher's claim?

1) Find the standardized test statistic z

z= ???

2) Reject or fail to reject the hypothesis and why???

Please explain all answers! Thank you!!

A researcher claims that the mean of the salaries of elementary school teachers is greater than the mean of the salaries of secondary school teachers in a large school district. The mean of the salaries of a random sample of 26 elementary school teachers is $48,250 and the sample standard deviation is $3900.

An investigator thinks that college students who pay for most of their own education study more than college students whose parents pay for most of their education. He gathers information on students regarding who is paying the greater portion of their college bills in order to put them into groups (parents pay (P) or student pays (S)) and also on the number of hours they report studying per week. Choose the type of test you should use to test this...

The state of California conducted an experiment with college students. Teachers and students were randomly assigned to be in a regular sized class or a small sized class. The dependent variable is the student’s score on a math test (MATHSCORE). Let SMALL = 1 if the student is in a small class and SMALL = 0 otherwise. The other variable of interest is the number of years of teacher experience, given by TCHEXPER. Let BOY = 1 if the stu-...
