Answer:
Option A) 0.0074
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 110
Sample mean,
= 20
Sample size, n = 100
Alpha, α = 0.05
Population standard deviation, σ = 115.35
First, we design the null and the alternate hypothesis
We use two-tailed z test to perform this hypothesis.
Formula:
Putting all the values, we have

Now, we calculate the p-value from the standard normal table.
P-value = 0.0074
Thus, the correct answer is
Option A) 0.0074
Answer:
C.12 1/2
Step-by-step explanation:
5=2/5a
Multiply each side by 5/2 to isolate a
5/2 * 5 = 5/2 * 2/5 a
25/2 = a
12 1/2 = a
Answer is 33/ 1/3
6 2/3 divided by 1/5
20/3 divided by 1/5
20/3 times 5/1
100/3
33 1/3 :)
