Answer:
5/12
Step-by-step explanation:
1/4 (what he already read)= 3/12
1/3 (what he had left) = 4/12
12/12 (whole book) - 4/12 (what he has left to read)= 8/12 (what he already read+what he read during the day)
8/12 - 3/12 (what he already read)= 5/12 (what he read during the day)

Answer: 1.960
Step-by-step explanation:
The value of z we use to calculate a confidence interval with a (
) confidence level is a two-tailed test value i.e. represented by :-
Given : The level of confidence: 
Then, significance level : 
With the help of standard normal distribution table for z , we have
Hence, the value of z should be used to calculate a confidence interval with a 95% confidence level =1.960
