Answer:
Step-by-step explanation:
part a: time, student surf the internet
part b
Given that t<span>he
manager of Theatre A says that they usually go through about 15 cups of
popcorn kernels and about 5 cups of oil each weeknight.
Then, the ratio </span><span>value of oil to popcorn kernels for theatre A is 5 / 15 = 1 / 5.
Given that t</span><span>he manager of Theatre B says that they order 18 cups of oil and 72 cups of popcorn kernels each week.
Then, the </span>ratio value of oil to popcorn kernels for theatre B is 18 / 72 = 1 / 4.
Given that t<span>he manager of Theatre C says that their concessions use 6 cups of oil and 32 cups of popcorn kernels on a busy Saturday.
Then, the </span>ratio value of oil to popcorn kernels for theatre C is 6 / 32 = 3 / 16.
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
