Question

Suppose a study reported that the average person watched 3.95 hours of television per day. A random sample of 15 people gave the number of hours of television watched per day shown. At the 11​% 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 overbarxequals=4.587 hours and sequals=1.038 ​hours.) what Is the p value?

Answer 1

Here claim is that the amount of television watched per day last year by the average person differed from the value reported in the​ study.

So hypothesis is vs

Test statistics is

P value is TDIST(2.38,14,2)=0.0321

As P value is less than alpha=0.11, we reject the null hypothesis

Hence there is sufficient evidence to support the claim that the amount of television watched per day last year by the average person differed from the value reported in the​ study.
