- Salaries of Government Employees The mean salaryof federal government employees on the GeneralSchedule is $59,593. The average salary of 30 stateemployees who do similar work is $58,800 withs $1500. At the 0.01 level of significance, can it beconcluded that state employees earn on average less thanfederal employees?s nipb. In a manufacturing unit for electronic chips, Unit manufactures chips that are either defective (10%), normal (82%), or slightly defective (8%). The produced chip is passed through an automated inspection system which can detect and discard any chip which is obviously defective. What is the quality of the chip that makes it through the inspection machine?
- Your place of employment is trying to determine whether to allow its employees to work from home for2 days a week. Knowing that you’ve previously taken a statistics course, your boss asks you to “figure itout”. You create a survey to gauge employee interest in this area.1. Formerly, your place of employment has tried to give surveys to everyone, a census, but only a fewpeople responded to the email. Your new plan is to randomly choose some employees and administerthe survey yourself. You put everyone’s name on a numbered list and randomly choose numbers untilyou have your sample. What form of sampling is being described here?2. Suppose you want to estimate the percentage of employees who want to work from home. Doingsome research on the internet, you find a recent study that found that 72% of employees prefer a hybridremote-office model. Using that value as your sample proportion, ?̂, estimate how many people youwould need to survey in order to estimate the percentage in your company…You work at a bank and are asked to recommend the amount of cash to put in an ATM each day.

Devonte’ Graham joined the Charlotte Hornets as rookie for the 2018-19 season and put up a three-point percentage of 28.1%. Fans are curious as to whether he will have a better or worse three-point percentage this season. So far, he has made 31 three pointers out of 73 attempts. Test whether his three-point percentage is different from last season using a 0.02 level of significance.
