Answer:
The training does reduce response time at 0.05 level of significance
Step-by-step explanation:
Population mean for a population with normal distribution, where the standard deviation is known and the appropriate significant test is given then;
z=x-μ / δ/√n
where
μ= 9 minutes
x=8 minutes
δ= 4.2
n= 36
Applying the formula;
z= 8-9 / 4.2/√36
z= -1 / 4.2/6
z= -1 /0.7 = - 1.429
Perform the test where
H₀ : p=0.05 verse Ha : p < 0.05
Using the Z-table, find the probability that Z is less than -1.43.
You will find the probability of 0.0764 of Z being more than the value in test thus; there are high chances that results will be observed according to the null hypothesis
Answer:
The answer is a "Weather occurs because the climate is costantly changing"
The total distance of the route is 112miles.
Step-by-step explanation:
Let us consider the total distance of the route to be 'y'.
Given that,
The distance from Boston to the passengers station = (1/3) y
The passenger got down at a station after beyond his station which is 14 miles away and the remaining route from that station is (13/24) y
So the travelled route = y - (13/24) y
= (11/24) y
The travelled route is from Boston to a station beyond 14miles of his station.
We can write the above as,
(11/24) y = (1/3) y + 14
(11/24) y - (1/3) y =14
(11y - 8y) /24 = 14
3y/24 = 14
y/8 = 14
y = 14 x 8
y = 112 miles
The total distance of the route is 112 miles
