A test was made of H0: μ1 = μ2 versus H1: μ1 < μ2. The sample means were x1-bar = 11 and x2-bar = 9, the sample standard deviations were s1 = 7 and s2 = 5, and the sample sizes were n1 = 15 and n2 = 13. Is H0 rejected at the 0.05 level? (Hint: First compute the value of the test statistic.)

Yes or No

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
