Suppose that BC financial aid alots a textboolk stipend by claiming that the average textbook at BC bookstore costs $ 94.98. You want to test this claim The null and alternative hypothesis in symbols would be: OHo:p 2 94.98 Hi:p94.98 Оно: р-94.98 Hi:p94.98 OHo H 94.98 H1 : μ > 94.98 Ho:p 94.98 Hi:p> 94.98 H0 : μ 94.98 H 94.98 0H0: μ > 94.98 H1: 94.98

Answer #1

Please don't hesitate to give a "thumbs up" in case the answer has helped you.

pop. mean = 94.98

Ho: Mu = 94.98
Ha: Mu != 94.98

The null hypothesis in words would be:
4th option is correct:The average price of all textbooks from the store is $94.98

Also given is :

n = 190
Sample mean = 95.78
Stdev =28.2

Point estimate= sample mean ( because the sample mean is a unbiased estimator of pop. mean ) = 95.78

The 90% Confidence interval is : 1.645

So, 90% CI is 94.98 +/- 1.645*28.2/sqrt(190)

= 91.615 to 98.345

Since the sample mean (of 95.78) lies between the 90% Confidence interval ( 91.615, 98.345) we conclude that we fail to reject the null hypothesis
