Listed below are the numbers of years that popes and british monarchs lived after their election or coronation (based on data from computer-interactive data analysis, by lunn and mcneil, john wiley & sons). treat the values as simple random samples from a larger population. use 0.01 significance level to test the claim that the mean longevity from popes is less than the mean longevity for british monarchs after coronation. popes 2 15 32 25 11 8 17 19 5 15 0 26 kings & queens 17 6 13 12 13 33 59 10 7 63 9 25 36 15 i. state the appropriate method for testing this claim. ii. the null and research hypothesis iii. obtained value iv. critical value v. conclusion (accept or reject the null

Use a hypothesis test for difference of 2 means

We reject the null hypothesis

Step-by-step explanation:

We will use a hypothesis test for the difference of 2 means, where the population variances are unknown and not assumed equal.  (The problem didn't tell us that the variances are equal, so we can't assume they are).  

We first need to find the sample means and since we don't know the population variances, we need to find the sample variances as well.

See first attached photo for the calculations of these values...

See second attached photo for the hypothesis test...

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
