Question 2 1 pts A customer service representative has a target of resolving an issue in under 4 mins. They achieve their target for 90% of issues. In a shift, they handle 110 independent issues. What is the probability that, in one shift, they will achieve their target for fewer than 96 issues? Answer as a probability {between 0 and 1] to four decimal places. Question 3 1.5 pts In a simple random sample of 150 Canadians, it is found that 58 have tested positive for COVID at some point. Calculate the three components of a 90% confidence interval for the proportion of Canadians who have tested positive for COVID. Give answers to four decimal places. Only round at the final step for each calculation. sample proportion +/- (critical value)X(standard error) +/ - XQuestion 4 1.5 pts The United States Golf Association {USGA} would like to compare the mean distances associated with four different brands of golf balls when struck with a robotcontrolled driver (to ensure a consistent swing}. Create a boxplot using the data for the variables "Golf ball brand" and "Distance (m)" from the Excel sheet "Q 4". Make sure to clearly label the axes including measurement units whenever possible. Include the mean for each golf ball brand on the plot using a symbol. Change the ll colour so that it is easy to see all the features of the plot. You do not need to include a title. Create your plot in Excel. Right-click on the plot and "Save as Picture...". Save as a PNG orJPEG le. Then in the text box below, choose Insert > Image 2> Upload Image. If you are having trouble saving the image from Excel, click somewhere outside of the graph, then take a screenshot and crop it to include only the contents of the graph. Question 5 1.5 pts For a random sample pet owners, the linear relationship between monthly income and monthly spending on their pet(s] has a correlation co-efcient of 0.7. The distribution for monthly income has a mean of $5700 with a standard deviation of $530. The monthly spending on pets has a mean of $140 with a standard deviation of $75. Find the intercept and slope that would be used in the regression equation to predict monthly spending on pets from monthly income. Make sure to only round answers at the nal step of any calculations. Intercept = Answer to three decimal places; do not include any units. Slope = Answer to three decimal places; do not include any units. Question 6 Monthly spending on entertainment is recorded for different households and follows a Normal distribution with a mean of $243 with a standard deviation of $38. What is the value for monthly spending on entertainment above which 60% of observations would occur? Answer in dollars to the nearest cent (two decimal places]. Question 7 1.5 pts Students completing internships can book meetings of different lengths {either 30 minutes, 60 minutes, or 90 minutes} with their supervisor. 65% of the students book 30-minute meeting, 30% book 60-minute meetings, and 5% book 90-minute meetings. What is the expected length of time {in minutes} for one meeting? Answer to two decimal places as needed. Expected length of one meeting = minutes What is the standard deviation (in minutes] for the distribution of meeting times? Answer to two decimal places as needed. SD for the distribution of meeting times = mins Question 8 1 pts Hannah is planning to collect data to estimate the proportion of Vancouver residents who intend to regularly use the new Broadway subway/skytrain when it opens. A preliminary study found that 8% of Vancouver residents intend to regularly use the new Broadway subwastkytrain when it opens. She would like to collect enough data to construct a 99.9% condence interval with a margin of error of at most 2%. What is the minimum sample size she should collect? Answer as a whole number. Question 9 2 pts Two teachers, Maeve and Craig, are marking essays for the International Baccalaureate program. In a 4-hour shif't, Maeve is able to mark on average 13.1 essays with a standard deviation of 1.2. In a 4-hour shift, Craig is able to mark on average 12.8 essays with a standard deviation of 0.9. Assume both distributions are Normal. What is the probability that, working at the same time, Maeve and Craig are able to mark at least 27 essays in a 4-hour shift? Answer as a probability (between 0 and 1} to four decimal places. Show your calculations in your Excel le on the sheet for this question so that the instructor can award partial marks. Question 10 1.5 pts The scatterplot below shows the association between Revenue and Current value for 32 National Football League (NFL) teams. 4,500 4,000 3,500 3,000 2,500 Current value ($ million) 2,000 1,500 1,000 500 250 300 350 400 450 500 550 600 650 Revenue ($ million) Fill in the blanks to make the following sentence describing the scatterplot correct: The relationship is a [Select ]Fill in the blanks to make the following sentence describing the scatterplot correct: The relationship is a [ Select ] [ Select ] V relationship with [ Select ] VQuestion 11 Which of the data visualizations would be most appropriate for each goal! research question? a) Is there an association between being vegetarian and having a subscription to a yoga or meditation app? | [SE'E'C'E] b} How has quarterly revenue for a video streaming company changed from 2013 until now?
