If you would like to find the inequality to determine the number of full-time employees Tom must schedule, you can calculate this using the following steps:
n ... the number of full-time employees
260 <= 20 + n * 40
260 - 20 <= n * 40
240 <= n * 40
n >= 240/40
n >= 6 full-time employees
The correct result would be at least 6 full-time employees.
Using the z-distribution, as we are working with a proportion, the 95% confidence interval for the proportion of consumers who would buy the product at it's proposed price is (0.3016, 0.3830).
<h3>What is a confidence interval of proportions?</h3>
A confidence interval of proportions is given by:
In which:
- is the sample proportion.
In this problem, we have a 95% confidence level, hence, z is the value of Z that has a p-value of , so the critical value is z = 1.96.
179 out of 523 members indicated they would buy the new product at the proposed price, hence:
Then the bounds of the interval are found as follows:

Answer:
5/8.
Step-by-step explanation:
Prob( Card is > 5) = number of cards > 5 / total number of cards
= 5/8
