Answer:
Z-test is a statistical test used to check weather two means are significant or not for unknown variance and large sample size.
Z = (M - μ) ÷ √(σ² / n)
where, M = Sample Mean = 66.075
μ = Population Mean = 90
σ² = Population Variance = 15
Now, Calculating the value of Z-test:
Z = (66.075 - 90) ÷ √(225 ÷ 40)
Z = -23.925 ÷ 2.37171
Z = -39.06936
The value of Z is -39.06936.
The value of p is < .00001 at 90% confidence level.
If the p-value is less than value of α, We accept the null- hypothesis otherwise reject.
The result is significant at p < .10.
Thus, we accept the null hypothesis.

Answer:
n = (m-1)/(4-g)
Step-by-step explanation:
m= 4n-gn+1
Subtract 1 from each side
m-1= 4n-gn+1-1
m-1 = 4n -gn
Factor out n
m-1 = n(4-g)
Divide each side by (4-g)
(m-1)/(4-g) = n(4-g)/(4-g)
(m-1)/(4-g) = n
n = (m-1)/(4-g)
Answer:
Step-by-step explanation:
45% = 45/100 = 0.45
- 0.45x = 18
- x = 18/0.45
- x = 40
100% is $40
