A. In the standard normal and t distributions, the 95% confidence multiplier is equal to the 1-sided critical value.
b. In the standard normal and t distributions, the 1-sided 5% critical value is equal to the % confidence multiplier.

a. 1.645 multiplier = 5% critical value

b. 95

Step-by-step explanation:

Note that in statistical analysis probability principles are often used. The critical value from the critical region indicates whether the statistician should reject or accept the null hypothesis.

Note that the confidence multiplier is a constant that shows the number of standard deviations in a normal curve; the  deviation standard implies the measure of difference between the observed value of a variable and some another value.

the first one, all those points on the line just make a strait line.
