1) the mean cost of a steak, broccoli, and ride at the grocery store is $13.04. a sample of 100 restaurants had a mean price of $12.75 and a standard deviation of $2 for the same meal. run a hypothesis test to determine if it is cheaper to eat at a restaurant than to cook the meal yourself!

Since p >0.05 at 5% significance level we reject that it is cheaper to eat at a restaurant than to cook the meal yourself!

Step-by-step explanation:

Given that the mean cost of a steak, broccoli, and ride at the grocery store is $13.04.

Sample size n = 100

Sample mean =

Std error of sample =

(Left tailed test)

Mean difference =

Test statistic = t = mean diff/std error

=

p value one tailed =0.075

Since p >0.05 at 5% significance level we reject that it is cheaper to eat at a restaurant than to cook the meal yourself!
