Answer:pretty sure 1 is 23 and 2 is 211200
Step-by-step explanation:
1. 92/4 is 23
2. Just used a calculator on
The group of tiles represent answer A. There are 6 x² tiles, 3 x tiles, and 1 tile.
Well, to calculate that, you have to multiply the number of bats by the "number" version of 31.5 %, which once you multiply them together, it comes out to be about 149 (148.995)
The answer would be B, ||
Answer:
H0 : μ = 4.50
H1 : μ > 4.50
Test statistic = 1.525
we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.
Step-by-step explanation:
H0 : μ = 4.50
H1 : μ > 4.50
Test statistic :
(xbar - μ) ÷ s/sqrt(n)
(4.94 - 4.50) ÷ 2.10/ sqrt(53)
0.44 / 2.10/ sqrt(53)
= 1.525
α = 1 - 98% = 0.02
Decision region :
Reject H0 ; if Pvalue < α
Pvalue = p(Z < 1.525) = 0.936
Pvalue = 0.936
Since Pvalue > α ; We fail to reject H0
Hence, we conclude that there is no sufficient evidence to conclude that the mean wait time for customers is longer than 4.50.
