let's think about it, let's divide say hmmm 15 by 0, in a fraction
now, how can you take any pieces of a pie that's non-existent? I mean that requires magic!!.
now, let's do it using a simple long division, 15 ÷ 0, so 0 is the divisor, anything times 0 is 0, what is our first digit in the quotient to get 15? 0 * 15 = 0, 0 * 1,000,000 = 0, there isn't any number we can possible use to get a quotient.
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.
