Answer:
There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes
Step-by-step explanation:
H0 : μ = 3.8
H1 : μ < 3.8
Test statistic :
(x - μ) ÷ s/sqrt(n)
(3.7 - 3.8) ÷ 0.6/sqrt(60)
Test statistic = - 1.29
The Pvalue from test statistic :
P(z < -1.29) = 0.0985
Reject Null if
Pvalue < α
0.0986 > 0.01 ; Hence, we fail to reject the null ;
There is no significant evidence to conclude that the mean waiting time is less than 3.8 minutes
Answer:
A Subtract 6 from 27 then divide by 3
Step-by-step explanation:
3B + 6 = 27
3B = 21
B = 7
so you subtract 6 from 27, then divide by 3
The correct answer is (5m^50 - 11n^8) x (5m^50 + 11n^8)
