The t value for a 95% confidence interval estimation with 24 degrees of freedom is

the value us 2.064

Step-by-step explanation:

To determine the t value, we would need the t distribution table. Since degree of freedom is known as 24, we would determine alpha/2

A 95% confidence level is 95/100 = 0.95

1 - alpha = 0.95

alpha = 1 - 0.95

alpha = 0.05

alpha/2 = 0.05/2 = 0.025

this is the area to the left. The area to the right 1 - 0.025 = 0.975

alpha/2 = 0.975

Looking at the t distribution table, the t value is

2.064

they will manufacture 8496 cars

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
