Dawn works at a theme park and is monitoring the wait times for different rides. Dawn created the spreadsheet below. What is the relationship between the number
of people in line and the wait time?
Rides
Whirly-Twirly
Skyline

Number Waiting In Line
20
40
80
100
Wait Time (in minutes)
4
8
16
20
For every 20 people in line, the wait time increases 5 minutes.
For every 20 people in line, the wait time increases 4 minutes.
For every 4 people in line, the wait time increases 20 minutes.
For every 40 people in line, the wait time increases 16 minutes.

What is the vertex form of f(x) = x2 + 6x + 3

(20 points) a bank has been receiving complaints from real estate agents that their customers have been waiting too long for mortgage confirmations. the bank prides itself on its mortgage application process and decides to investigate the claims. the bank manager takes a random sample of 20 customers whose mortgage applications have been processed in the last 6 months and finds the following wait times (in days): 5, 7, 22, 4, 12, 9, 9, 14, 3, 6, 5, 15, 10, 17, 12, 10, 9, 4, 10, 13 assume that the random variable x measures the number of days a customer waits for mortgage processing at this bank, and assume that x is normally distributed. 2a. find the sample mean of this data (x ě…). 2b. find the sample variance of x. find the variance of x ě…. for (c), (d), and (e), use the appropriate t-distribution 2c. find the 90% confidence interval for the population mean (îľ). 2d. test the hypothesis that îľ is equal to 7 at the 95% confidence level. (should you do a one-tailed or two-tailed test here? ) 2e. what is the approximate p-value of this hypothesis?
