Answer:
<em>Part A: 45</em>
<em>Part B: 22</em>
Step-by-step explanation:
Answer:
We will not reject the null hypothesis.
There is not enough evidence to support the claim that the mean age of death
-row inmates is different from 36.2 years.
Step-by-step explanation:
Consider the provided information.
The average age of an inmate in death row in 1989 was 36.2 years of age.
The sociologist collects a sample of 32 death-row inmates and finds that their mean age is 38.9 with a standard deviation of 9.6 years. Test the Sociologist’s claim at 0.05 significance level.
From the above information.
,
, , , n=32
This is a two sided test, with df = 32-1 = 31 and the critical values are .
Now find the z score as shown:
Substitute the respective values:
Since, 1.591 doesn’t lie in the critical region, hence we will not reject the null hypothesis.
There is not enough evidence to support the claim that the mean age of death
-row inmates is different from 36.2 years.
Answer:
-2
Step-by-step explanation:
We have to multiply 10 and
Here we have to distribute the negative sign.
Distributive property = -(a) = -a
Using the above property, we get =
Now we have to multiply 10 and
= 10 ×
=
=
Now we have to divide -10 by 5.
= -2
104 total - 32 cookies = 72 brownies.
Ratio of A to B is A/B.
So ratio of brownies to cookies is 72 brownies / 32 cookies = 2.25
