Question

Suppose a study reported that the average person watched 4.35 hours of television per day. A random sample of 15 people gave the number of hours of television watched per day shown. At the 5​% significance​ level, do the data provide sufficient evidence to conclude that the amount of television watched per day last year by the average person differed from the value reported in the​ study? (Note: x overbarequals3.947 hours and sequals1.499 ​hours.) 3.0 3.4 6.2 2.4 4.1 2.5 4.6 2.1 6.2 3.2 3.1 5.8 2.8 6.3 3.5

Set up the hypotheses for the one-mean t-test.

The test statistic is t =

Identify the critical value(s)

What is the conclusion for the hypothesis

Answer 1

We have to test the one mean t test for this we have to find t test statistic and t critical value , then after comparison of both to take conclusion.
