Answer: There are 24 traffic lights on Berry Boulevard.
Step-by-step explanation:
Since we have given that
Total length of road =
Number of roads on every = 2
So, According to unitary method,
In every , number of roads = 2
In every 1 mile, number of roads =
So, in every the number of roads =
Hence, there are 24 traffic lights on Berry Boulevard.
Answer:
Step-by-step explanation:
Answer:
A.) No
B.) test statistic = - 3.108
Check explanation
Step-by-step explanation:
H0: m = 105 versus H1: m ≠ 105
Sample size, n = 35, since we have a large sample size, greater than 30.
B.)
xbar = 101.9 ; s = 5.9
Test statistic :
T = (xbar - μ) ÷ (s/√n)
T = (101.9 - 105) / (5.9/√35)
T = - 3.1 / 0.9972820
Test statistic = - 3.11
Pvalue from Tstatistic, df = 34
Pvalue = 0.003772( Pvalue calculator)
Pvalue is the probability of obtaining a value more extreme or exactly that of the test statistic.
At α = 0.01
Pvalue < α ; We fail to reject the Null
2b -1 = 11
⇔ 2b = 12
⇔ b = 6
