Step-by-step explanation:
Answer:
1.4000 ;
0.0807 ;
1.69 ;
Fail to reject the Null
Step-by-step explanation:
Given :
μ = 21 minutes
x = 22.4 minutes
Sample size, n = 36
Standard deviation, s = 6
H0: μ ≥ 21
H1: μ < 21
Test statistic : (x - μ) ÷ s/sqrt(n)
Test statistic : (22.4 - 21) ÷ 6/sqrt(36)
Test statistic : 1.4 ÷ 1
Test statistic = 1.4000
Pvalue : Using the Test statistic value at α = 0.05 ; One - tail test = 0.0807
The t critical value using a critical value calculator ; DF = (n - 1) = 36 - 1 = 35 ; α = 0.05 = 1.69
Decision region :
Reject H0 if
|Test statistic| > |critical value|
1.4 < 1.69
Hence, we fail to reject H0
There isn't enough evidence they delivery time has been reduced below previous mean
Answer:
385.875 cm^3
Step-by-step explanation:
3.5/2 = 1.75
3.5^2 - 1.75^2 = 9.1875
3.5 * 9.1875/2 = 16.078
16.078 * 6 * 4 = 385.875
Yes zero is the answer because they have the same values that are opposing.
The tax bracket that Monica falls partly into is the $0 - $9,950 bracket. This is because her taxable annual earnings after is less than $9,950. hence she will be paying 10% of what's taxable.
