Your Place Of Employment Is Trying To Determine Whether To Allow Computer Science Essay Help

(6.) Your place of employment is trying to determine whether to allow its employees to work from home for 2 days a week. Knowing that you’ve previously taken a statistics course, your boss asks you to “figure it out”. You create a survey to gauge employee interest in this area.

A.) Formerly, your place of employment has tried to give surveys to everyone, a census, but only a few people responded to the email. Your new plan is to randomly choose some employees and administer the survey yourself. You put everyone’s name on a numbered list and randomly choose numbers until you have your sample. What form of sampling is being described here?

B.) Suppose you want to estimate the percentage of employees who want to work from home. Doing some research on the internet, you find a recent study that found that 72% of employees prefer a hybrid remote-office model. Using that value as your sample proportion,
, estimate how many people you would need to survey in order to estimate the percentage in your company that would prefer to work at home, within 5 percentage points, with 95% confidence.

C.) Because of practical considerations you ultimately decide to survey 100 people and find that 75 of them would prefer to work at home to some extent. When your boss asks you “What percentage of employees at this company want to work from home?”, what percentage do you tell him?

D.) He seems flustered and asks “That’s higher than I thought! Since you didn’t ask everyone in the company, how do you know that your numbers are correct?” What do you say in response?

E.) Still unconvinced, you calculate a 95% confidence interval to estimate the percentage of employees who want to work from home. Show the calculation below or indicate what technology you used and what values you put into the calculator or Excel.

F.) Explain what this confidence interval means to your boss, who has never taken a statistics class.

G.) Explain why the confidence interval is a better than just using the point estimate that you gave him from question #3.

H.) Your job is planning on expanding its benefits package to include some amount of student loan forgiveness. Your survey also asked if the employees had student loans and how much they currently owed. Your survey found that out of the 100 people surveyed, the mean amount of student loan debt was \$32,425, with a standard deviation of \$16,824. Estimate the mean student loan debt for all employees in your company, with 95% confidence using your sample data. Use the t-distribution here.

Hello this was question six on a 8 question assignment that I had received last week. I had gotten most parts of this question incorrect and was hoping to have someone explain the process, formulas, and strategies used to solve this question. When it came to the actual mathematical questions apparently I had plugged in the numbers incorrectly or something and they were marked wrong. I honestly did not know how to explain why my answer was correct or why I was certain at the time of my answers, besides look at the math. I would truly appreciate any information given so this mistake does not occur during my test tomorrow. PLEASE I REALLY NEED HELP UNDERSTANDING!! This is urgent as I have to review all night and would like to use the feedback I received on this assignment.

Lastly, I wanted to say thank you and that I appreciate the time you take out to help me with these. ## two Intervals Are Given, A And B, For The Same Value Of Essay Help

15. This problem involves the Boston data set, which we saw in the lab for this chapter. We will now try to predict per capita crime rate using the other variables in this data set. In other words, per capita crime rate is the response, and the other variables are the predictors. (a) For each predictor, fit a simple linear regression model to predict the response. Describe your results. In which of the models is there a statistically significant association between the predictor and the response? Create some plots to back up your assertions. (b) Fit a multiple regression model to predict the response using all of the predictors. Describe your results. For which predictors can we reject the null hypothesis Ho : 8, = 0? (c) How do your results from (a) compare to your results from (b)? Create a plot displaying the univariate regression coefficients from (a) on the r-axis, and the multiple regression coefficients from (b) on the y-axis. That is, each predictor is displayed as a single point in the plot. Its coefficient in a simple linear regres- sion model is shown on the r-axis, and its coefficient estimate in the multiple linear regression model is shown on the y-axis. (d) Is there evidence of non-linear association between any of the predictors and the response? To answer this question, for each predictor X, fit a model of the form Y = Bo BIX B2X2 B3X3 c.
