Complete question is;
Suppose we are testing the null hypothesis H0: μ = 20 and the alternative Ha: μ ≠ 20, for a normal population with σ = 5. A random sample of 25 observations are drawn from the population, and we find the sample mean of these observations is x¯ = 17.6. The P-value is closest to:
a. 0.0668.
b. 0.0082.
c. 0.0164.
d. 0.1336
Answer:
Option D
Step-by-step explanation:
We are given;
Null hypothesis; H0: μ = 20
Alternative hypothesis; Ha: μ ≠ 20
Population Standard deviation; σ = 5
Sample size; n = 25
Sample mean; x¯ = 17.6
Let's find the z-score from the formula;
z = (x¯ - μ)/(σ/√n)
z = (17.6 - 20)/(5/√5)
z = - 1.073
From online p-value from z-score calculator attached, using z = -1.073; two tailed hypothesis; significance value of 0.05,we have;
The P-Value is 0.283271.
Looking at the given options, the closest to the p-value is option D

A health club charges a one-time sign up fee of $99.99 plus a monthly charge of $12.75. A new member paid a total of $189.24 when she signed up. For how many months did she pay?
(A)7
(B)15
(C)22
(D)77
Answer: A. 7
Step-by-step explanation:
189.24 - 99.99 = 89.25
89.25 ÷ 12.75 = 7
Based on the information given the number of months did she pay is (A)7.
First step is to calculate the fee amount paid
Amount=$189.24 -$99.99
Amount=$89.25
Second step is to calculate for number of months
Number of months=$89.25 ÷ $12.75
Number of months= 7 months
Inconclusion the number of months did she pay is (A)7.

Reading a text message takes your eyes off the road for about 4.6 seconds according
to a recent study. If you are traveling 60 mph and check a text message while you
are driving, how far do you travel (in feet) with your eyes not on the road? Round
your answer to the nearest foot.
Answer:
d = 404.8 feet
Step-by-step explanation:
We take our eyes off the road for about 4.6 seconds according to a recent study.
Speed, v = 60 mph
We need to find the distance travel by you with your eyes not on the road. Let it is d.
Speed, v = d/t
d = vt
We know that, 1 mile = 5280 feet
[tex]d=\dfrac{60\times 5280\ \text{feet}}{3600\ s}\times 4.6\ s\\\\=404.8\ \text{feet}[/tex]
Hence, the required distance is 404.8 feet.
Sam has 43 pencils. Abby has twice as many pencils as Sam. How many pencils do they have altogether?
Answer:
86 altogether.
Step-by-step explanation:
Since she has twice as many, you would do 43 x 2 = 86
Answer:
129
Step-by-step explanation:
Sam = 43 (s)
Abby = 2s
s + 2s = 3s
3s, when s = 43, equals 129

Step-by-step explanation:
if you look at the equation, you can see there is an equal sign, so both costs must be the same. this marks out c and d.
each side of the equation has to be paired with one another. 16 and .55 have to be together, and 22 and .25 have to be together. in b, they are mixed up, so that makes it wrong.
