Sebastian signed up for a streaming music service where there's a fixed cost for monthly membership and a cost per song downloaded. His
total cost per month is given by the equation c = 1.25x + 4.99,
where represents the number of songs he downloads and c
represents the total cost, in dollars and cents. What is the meaning of
the c-value when x = 1?
The cost to use the service for one month if zero songs are
downloaded.
O The total cost per month assuming one song is downloaded.
The cost to download 100 songs.
O How much the streaming service charges per downloaded song.

(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?
