Answer:
The critical value approach and the p-value approach gave the same result.
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 4 hours
Sample mean, = 4.5
Sample size, n = 460
Alpha, α = 0.051
Population standard deviation, σ = 1.00 hour
First, we design the null and the alternate hypothesis
We use One-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have
Now,
Since,
We reject the null hypothesis and accept the alternate hypothesis. Thus, low-income families are exposed to more than 4.0 hours of daily background television.
p value at z-stat 3.87 is 0.000054. Since p-value is less than the significance level. We reject the null hypothesis.
Hence, the critical value approach and the p-value approach gave the same result.
Answer:
Hello,
If f(x)=5x-13, then f^-1(x)=
have good day
Step-by-step explanation:
Ok so 20ft real
finid how many cm the restaurant is in scale
1foot:2.4cm
20foot:?
obviously multiply both sides by 20
20foot:2.4cm times 20
20ft:48cm
it is 48cm tall
how many bottle caps needed to get to 48
48=height of 1 bottle cap times numer of bottle caps
height of 1 cap=1.2cm
48cm=1.2cm times number of bottle capse
divide both sides by 1.2cm
40=number of bottl capse
needs to be 40 caps tall
