An employer wants to predict the number of sick days employees
will take depending on whether they have young children or not.
Which of the following is the correct model for mean number of
sick days, E(y), as a function of whether or not the employees
have young children?
A. E(y) = β0 + β1x1 + β2x2, where x1 = 1 if the employee has
young children, 0 otherwise and x2 = 1 if the employee has young
children, 0 otherwise
B. E(y) = β0 + β1x + β2x2, where x = number of young children
C. E(y) = β0 + β1x, where x = number of young children
D. E(y) = β0 + β1x, where x = 1 if the employee has young children, 0 if the employee has no young children

The mean number of sick days per employee taken last year by all employees of a large city was 10.6 days. A city administrator is investigating whether the mean number of sick days this year is different from the mean number of sick days last year. The administrator takes a random sample of 40 employees and finds the mean of the sample to be 12.9. A hypothesis test will be conducted as part of the investigation. Which of the following...

The Human Resource Manager at Crown Point Hotel is looking at the number of sick days that all employees at the hotel have been taking over the past 6 months. She has found that the number of sick days follows a normal distribution with a mean of 6.7 sick days and a variance of 1.44 sick days. What is the probability that in a six-month period an employee takes: More than four and a half (4.5) sick days? (5 marks)...

A county real estate appraiser wants to develop a statistical model to predict the appraised value of houses in a section of the county called East Meadow. One of the many variables thought to be an important predictor of appraised value is the number of rooms in the house. Consequently, the appraiser decided to fit the linear regression model: E(y) = β0 + β1x, where y = appraised value of the house (in thousands of dollars) and x = number...
Regression Model (Statistics)
The CFO of the company would like to use the number of years employees have been with the company to predict the employees’ salaries. To that end, the CFO decided to fit the linear regression model E(y) = β0 + β1x, where Y = the salary of an employee (in thousands of dollars) and X = the years employed with the company. Using data collected for a sample of n = 35 employees of the company, the following result was...

One of the many variables thought to be an important predictor of appraised value is the number of rooms in the house. Consequently, the appraiser decided to fit the simple linear regression model, y=β0+β1x, where y=appraised value of the house (in $thousands) and x=number of rooms.
