Question Question 17 (1 point) A company manufacturing computer chips finds that 8% of all chips manufactured are defective. In an effort to decrease the percentage of defective chips, management decides to provide additional training to employees. After training was implemented, a sample of 450 chips revealed only 27 defects. We would like to use hypothesis testing to investigate if the additional training was effective in lowering the defect rate. What is the p-value for this test? 0.0465 0.0485 0.0594 0,0706

A personnel consultant was hired to study the influence of sick-pay benefits on absentee-ism. She randomly selected samples of hourly employees who do not get paid when out sick and salaried employees who receive sick pay. Using the data on the number of days absent during a one-year period, test/provide the following: Hourly: 1,1,2,3,3,6,7,4,0,4 Salaried: 2,0,4,2,10,12,5,4,5,8 (Hint: Use N-1) Would you reject or retain the null hypothesis (that hourly and salaried employees do not differ) at 0.05 for a one-tailed test? Group of answer choices Retain the null hypothesis Reject the null hypothesis No answer text provided. Cannot be determined with the information provided.

A researcher studying alcohol consumption in North American cities finds a sign ificant, positive cor relation between the number of Baptist preachers and alcohol consumption. Is it reasonable for the researcher to conclude that the Baptist preachers are consuming most of the alcohol? Why or why not?

GENG8020 Assignment #4 Earned Value Analysis Your project team has been tasked with assembling 100 data acquisition systems in 8 days. The estimated cost of each unit is $10,000, for a total project cost of $1,000,000 The following table provides the schedule and cost estimates determined at the start of the project: Day 1 Day 2 Day 3 Day 4 Day 5 Day 6 Day 7 Planned Day 8 10 12 15 18 15 15 10 5 number of built systems Estimated 100,000 120,000 150,000 180,000 150,000 150,000 100,000 cost for 50,000 the day (5) Estimated 100,000 220,000 370,000 550,000 700,000 850,000 950,000 cumulative 1,000,000 cost (5) What is the budgeted cost of work scheduled (BCWS)? $550,000 What is the budgeted cost of work performed (BCWP)? $500,000 What is the actual cost of work performed (ACWP)? $500,000 Calculate the schedule variance (SV). SV = 550,000 - 500,000 = $50,000 Calculate the cost variance (CV). CV = 500,000 - 500,000 = 0 Calculate the Schedule Performance Index (SPI). SPI = 550,000 / 500,000 = 1.1 Calculate the Cost Performance Index (CPI). CPI = 500,000/500,000 = 1
