Answer:
13/6 or ≈ 2.17
Step-by-step explanation:
2 + (1/6)
= 2*6 / 6 + 1/6
= 12/6 + 1/6
= 13/6 or ≈ 2.17
Hope this help you :3
Answer:
a) T test
b) Claim
because critical value is not equal to test statistic then reject null hypothesis
Step-by-step explanation:
Construction of hypothesis
H₀ : p = 75
H₁ : p ≠ 75
Here Standard deviation = 7
sample = n = 50
Average = x-bar = 78
Level of significance:
∝ = 5% = 0.05
Degree of freedom:
df = n-1
= 50 -1 = 49
Critical value :
± 1.96
a) T test
test t is used as average X mean is used
Test Statistic:
t = X₂ - X₁ / Sd /√n
= 78 - 75 / 7/√50
=3.0304
Critical region :
We take two tail T test
test statistic is in reject interval. Reject H₀
b) Claim
because critical value is not equal to test statistic then reject null hypothesis
The number is x
x of 55% = 94
x * (55/100) = 94
x = 9400 / 55
x = 170.91
