Answer:
P-value = 0.0368
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 101.5
Sample mean, = 106.4
Sample size, n = 30
Alpha, α = 0.05
Population standard deviation, σ = 15
First, we design the null and the alternate hypothesis
We use One-tailed(right) 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, students in Pennsylvania have an IQ that is significantly greater than the state average.
P-value can be calculated with the standard normal table.
P-value = 0.0368
P-value is lower than the significance level.
Answer:
15 i belive cause you would need that much people
well , I guest you should add them all together
103.5 + 320.75+186.30 = 610.55 miles for all three days
I hope that's help !
U have the to use the formula
y2-y1/x2-x1
that will get u the slope
-10-8 = -18
-9-1= -10
this give u 18/10 which can be simplified to 9/5
so the slope is 9/5
hope this helps!
