Answer:

We can reject the null hypothesis. There is significant evidence that p<0.31 at α = 0.01

Step-by-step explanation:

To test the the claim p < 0.31, null and alternative hypotheses are:

H_{0}: p=0.31

H_{a}: p<0.31

For α = 0.01, one tailed test critical value is -2.33

For z=-3.36 , p value is ≈ 0.0004

Since p-value<significance level (0.0004<0.01), we can reject the null hypothesis. There is significant evidence that p<0.31 at α = 0.01

A salesperson obtained a systematic sample of size 25 from a list of 500 clients. To do​ so, he randomly selected a number from
dangina [55]

Answer: Option 'D' is correct.

Step-by-step explanation:

Since we have given that

First term = 13

Increase each time = 20

Number of clients = 25

So, it forms an arithmetic progression:

So, 25 th term would be

a_{25}=a+(n-1)d\\\\a_{25}=13+(25-1)\times 20\\\\a_{25}=13+24\times 20\\\\a_{25}=13+480\\\\a_{25}=493

Hence, list would look like 13,33,............493.

Therefore, Option 'D' is correct.
