## Question

###### 15)According to the 444 Daily Fuel Gauge Report; the state of California average price for regular unleaded gasoline on January 2nd; 2018 was S3.11.A week later; random sample of 12 gas stations across Orange County yielded the following prices for - regular unleaded gasoline:s3.093.19 3.09 3.193.04 2.95 335 3.15333Use normal probability plot to assess whether the sample data above could have come from population that is normally distributed_ The data appear to be approximately normally distribu

What is the sampling distribution of T 24 normally distributed with mean of 50 and standard deviation of 0.632 B) normally distributed with mean of 50 and standard deviation of 44 approximately normally distributed with mean of 50 and standard deviation of 0.6324 8 approximately normally distributed with mean of 50 and standard deviation of 44 shape unknown with mean of 50 and standard deviation of 44 17) The amount of money collected by snack bar at a large university has been recorded daily for the past five ~ years_ Records indicate that the mean daily amount collected is $3900 and the standard deviation is S600. Thex distribution skewed to the right due to several high volume days (including football game days) Suppose- that 100 days were randomly selected from the five ears and the average amount collected from those days ~ was recorded_ Which of the 'following describes the sampling distribution of the sample mean? - normally distributed with mean of S3900 and standard deviation of S60 B) normally distributed with mean of S3900 and standard deviation of S600e C) approximately normally distributed with mean of S3900 and standard deviation of $604 D) skewed to the right with mean of $3900 and standard deviation of S600~ E) skewed to the right with mean of $3900 and standard deviation of S60- 18) The reasoning for your answer in Problem #17 is: = the law of large numbers ~ the central limit theorem- 1 the 68-95-99_ rule the fact that probability is the long-run proportion of times an event occurs - the sampling distributione
