Solution

First question i open in many image viewer. But it is not readable.

Question 18:

Option 1 is correct because sample size is large enough.

Question 19:

Since test is two tailed so P-value of the test will be

2P(z>2.4)=0.164

Hence, 2nd option is correct.

Question 20:

For p-value 0.001 becuase it is less than 0.01. Hence, 3rd option is correct.
