Line with point P and equidistant arcs drawn on either side of point P, creating points D and F such that point P is between points D and F; an arc has been created from point F on one side of the line. According to the partial construction shown, what is the next step in constructing a line perpendicular to a point on the line? Place compass at point D, and draw an arc that intersects the arc above line DF. Place compass at point F, and draw an arc that intersects the arc above line DF. Place compass at point P, and draw an arc above line DF Place compass at point P, and draw an arc below line DF

(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?
