Answer 1

Question

Chapter 3.4, Problem 104E

a.

To determine

Identify the percent of values that must be chopped off from each tail for the confidence interval of 95%.

a.

Expert Solution

Answer to Problem 104E

The percent of values that must be chopped off from each tail is 2.5%.

Explanation of Solution

In a 95% confidence interval, 95% of observation will be considered as the middle values and the remaining 5% of values has to be chopped off from both sides of the tail. Thus, from each tail, 2.5%(=5%2) of values has to be chopped off.

b.

To determine

Identify the percent of values that must be chopped off from each tail for the confidence interval of 90%.

b.

Expert Solution

Answer to Problem 104E

The percent of values that must be chopped off from each tail is 5%.

Explanation of Solution

In a 90% confidence interval, 90% of observation will be considered as the middle values and the remaining 10% of values has to be chopped off from both sides of the tail. Thus, from each tail, 5%(=10%2) of values has to be chopped off.

To determine

Identify the percent of values that must be chopped off from each tail for the confidence interval of 98%.

c.

Expert Solution

Answer to Problem 104E

The percent of values that must be chopped off from each tail is 1%.

Explanation of Solution

In a 98% confidence interval, 98% of observation will be considered as the middle values and the remaining 2% of values has to be chopped off from both sides of the tail. Thus, from each tail, 1%(=2%2) of values has to be chopped off.

d.

To determine

Identify the percent of values that must be chopped off from each tail for the confidence interval of 99%.

d.

Expert Solution

Answer to Problem 104E

The percent of values that must be chopped off from each tail is 0.5%.

Explanation of Solution

In a 99% confidence interval, the 99% of observation will be considered as the middle values and the remaining 1% of values has to be chopped off from both sides of the tail. Thus, from each tail, 0.5%(=1%2) of values has to be chopped off.
