Question 3: find the 99% confidence interval for the previous problem **Question:**Find a 99% confidence interval for the previous problem.**Options:**1. (30.19, 32.21)2. (30.26, 32.14)3. (31.195, 31.205)4. The sample size is too small to find a confidence interval. (Note: Ensure to refer to the context provided in the "previous problem" to select the most appropriate option.) A car manufacturer produces a new car that advertises an average of 30 MPG. The distribution of MPG of cars is normally distributed. The manufacturer will test 30 cars off the assembly line to find a confidence interval of the average MPG of their new vehicle to determine if it is close to 30. The average MPG of the 30 cars is 31.2 gallons with a standard deviation of 2 gallons. Find a 95% confidence interval for the average MPG of the new vehicle.Options:- (30.45, 31.95)- (30.48, 31.92)- (31.18, 31.22)- The sample size is too small to compute a confidence interval.
