Hello All! School Question: What does 2 halves equal?(i put this so my question will not get deleted)

So im back, my mother actually was WAY too busy for me to ask her about cutting my bangs. She has nothing to do TODAY. But she is on a call with her therapist. So im going to ask her today after the call. I feel very happy today because i have done nothing bad so far, AND i have nutella and my favorite sourdough pretzels. I have my therapy lesson today at 4 so i think i will be actually happy today! Also, i feel VERY happy because i have nutella :') i have never smiled THIS much in a while :))

Enjoy the colored picture of pusheen cat baking and my nutella "smiling" at you <3

DOGGIE Enjoy my doggie "Nala" :) She is 2 years old :D

(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?
