Answer:
Test statistic = 1.818
Reject H0
Step-by-step explanation:
H0 : μ = 90
H1 : μ > 90
xbar = 94 ; s = 22 ; n = 100
The test statistic : (xbar - μ) ÷ (s/√(n))
Test statistic = (94 - 90) ÷ (22/√100)
Test statistic = 4 ÷ 2.2
T = 1.818
The critical value :
At α = 0.10
Degree of freedom = n - 1 = 100 - 1 = 99
Tcritical(0.10, 99) = 1.290
Decison region :
Reject H0 if Test statistic > |Tcritical |
1.818 > 1.290
We reject H0
Answer:
x = $1 & y = $2.
Each doughnut cost $1 and hot chocolate cost $2.
The greatest common factor for 130 would be 130.
Factors of 130
1, 2 , 5 ,10,13, 26, 65 and 130
A factor is a number <span>that is multiplied with another produces a given number or expression. Lets look at factors of 16</span>
1x16 = 16
2 x 8 = 16
The factors are 1,2,8,16. When we multiply them we get 16. Also each one of these factors divide into 16 evenly too.
Answer:
Angle b is 90 degrees. If angle a is 42 degrees and it is a right triangle then angle b is 90 degrees
