I belive the answer is the 3rd one
Answer:
- we will reject H0:u=0.29 ( null hypothesis )
- Test static = -1.94, P-value ≈ 0.034
Step-by-step explanation:
Given data
significance level = 0.05
we will reject H0:u=0.29 ( null hypothesis )
This is because at 5% percent significance level the data gotten using excel
i.e. Test statistic = -1.94 and P-value = 0.034 it is evident that the charity used less than 29% of its donations for its expenses.
hi
You are making f ° h
f(x) = 9x-5
h(x) = 2x²
You must first calculate h(-5) : so remplace x by -5 in h :
h(-5) = 2 (-5)² = 2* 25 = 50
then apply f(x) to result : f(50) = 9 *50 -5 = 450 -5 = 445
Step-by-step explanation:
thanks for question mam.
