Question

Population Inferences

Answer 1

Answer:

Over 300 students did not support start time after 8:00am

Step-by-step explanation:

Given

$N = 600$ --- population

$n = 40$ --- sample

See attachment for dataset

Required [True/False]

Over 300  wants start time after 8:00am

First, we calculate the number of samples that wants start time after 8:00am

$x = 8:30am\ start + 9:00am\ start$

For sample 1

$x_1 = 18$

The corresponding value of x1 in the overall population is:

$X_1 = \frac{x_1}{n} * N$

$X_1 = \frac{18}{40} * 600$

$X_1 = \frac{18 * 600}{40}$

$X_1 = \frac{10800}{40}$

$X_1 = 270$

For sample 2

$x_2 = 19$

The corresponding value of x2 in the overall population is:

$X_2 = \frac{x_2}{n} * N$

$X_2 = \frac{19}{40} * 600$

$X_2 = \frac{19* 600}{40}$

$X_2 = \frac{11400}{40}$

$X_2 = 285$

None of X1 and X2 is greater than 300.

Hence, over 300 students did not support start time after 8:00am
