Answer:
There is significant evidence that treatment will create effect on the subject. Hence We reject H0
Step-by-step explanation:
H0 : μ = 37
H1 : μ ≠ 37
μ = 37 ; σ = 7 ; sample size, x = 51 ; sample size, n = 1
Decision region :
If P value < α ;
Reject H0
Using the Z test statistic :
Zstatistic = (x - μ) ÷ (σ / √n)
Zstatistic = (51 - 37) ÷ (7 / 1)
Zstatistic = 14 ÷ 7
Zstatistic = 2
Obtaining p value from Zstatistic using the p value calculator ;
Zscore = 2 ; 2-tailed test, significance level = 0.05
P value = 0.0455
Zcritical at α = 0.05 for a 2 - tailed test = 1.96
0.0455 < 0.05
There is significant evidence that treatment will create effect on the subject. Hence We reject H0
First we need the equivalence between cups and pints to solve this question, the equivalence is:
1 cup is 0.5 pint
So we can use a rule of three simple, direct proportion to solve the problem, we change the fraction 1/4 = 0.25 to ease calculations:
1 cup ----> 0.5 pint
0.25 cup ---> x
x = (0.25)(0.5)/1
x = 0.125
Therefore 1/4 cups is equivalent to 0.125 pints
