Step-by-step explanation
The answers in bold is what was required from the question.
the null hypothesis using symbol:-
H₀ : μ = 11.80
the alternative hypothesis using symbol:-
H₁: μ ≠ 11.80
This is a one tailed test. Given what you know, you will evaluate this hypothesis using a t test statistic.
Alpha level = 0.05
Sample size = n
Degree of freedom = n-1 = 40-1 = 39
To use the t distribution we will have to find the critical value from the t table this value is 1.685
But the question does not have sample mean and sample standard deviation. So I was unable to solve for the standard error
Answer:
18.95 x 4 =75.8
Step-by-step explanation:
James bought 4 t-shirts for 18.95, so you would multiply it and that would give you a sum of 75.8 or you could also add 18.95 , 4 times to get 75.8.

(1,2) they have one input but two different outputs so it is not a function
