This applet illustrates 95% confidence intervals for samples from a normal distribution with known variance. (a) When taking 100
Kay [80]

Answer:

Step-by-step explanation:

When taking 100 samples of size 30 or greater from a population, exactly 95 of them will create a confidence interval that contains the true population mean. True or false?

This statement is false, or better still, ambiguous. 100 samples of size 30 (or greater) each, means 300 total and it can't be just 95 of them that will contain the true population mean.

A video store rents new movies for $5 and older movies for $4. The owner wants
AnnyKZ [126]

Answer:

2480 new movies

Step-by-step explanation:

1) First you need to find out how much money the 400 older movies made.

400*4=1600

2) Next subtract that amount from the amount of revenue that the wants.

14000-1600=12400

3) Divide the amount of leftover money by the amount that a new movie costs to rent

12400/5=2480

This means that in order to reach the desired amount of revenue the store must sell 2480 new movies.
