Write down the answer and bold it with underline so I don't get confused. I only need the answer no need for step by step explanation. Thank you.

@ Question 23 - | Linear Regression Application, Interpolation and Extrapolation Use the data and story to answer the following questions The table below shows the number of state-registered automatic weapons and the murder rate for several Northwestern states. x| 11.3 8.9 7.2 | 3.8 | 2.9 | 2.6 [ 2.0 | 0.6 y | 13.9 | 11.2 | 10.4 | 7.5 | 6.3 & 6 | 4.4 I = thousands of automatic weapons Y = murders per 100,000 residents Use your calculator to determine the equation of the regression line. (Round to 2 decimal places) Determine the regression equation in y = ax + b form and write it below. A) How many murders per 100,000 residents can be expected in a state with 1.6 thousand automatic weapons? Answer = | |Ruund to 3 decimal places. B) How many murders per 100,000 residents can be expected in a state with 9.6 thousand automatic weapons? Answer = | |Ruund to 3 decimal places. Submit Question Question 12 v 7) = | For the random variable X, give the following: mean: p=| ' variance: 02 :| ' standard deviation: o =| ' @ Question 17 - A psychiatrist is interested in finding a 95% confidence interval for the tics per hour exhibited by children with Tourette syndrome. The data below show the tics in an observed hour for 15 randomly selected children with Tourette syndrome. Round answers to 3 decimal places where possible. [n]8]1]1Jo]s]7]1muJz2]Jof11]2]4]0]12 a. To compute the confidence interval use a distribution. b. With 95% confidence the population mean number of tics per hour that children with Tourette syndrome exhibit is between | and ' | c. If many groups of 15 randomly selected children with Tourette syndrome are observed, then a different confidence interval would be produced from each group. About percent of these confidence intervals will contain the true population mean number of tics per hour and about| ' percent will not contain the true population mean number of tics per hour
