road averages 2,115 vehicles per day with a standard deviation of 485 vehicles per day. A traffic counter was used on this road on 38 days that were randomly selected. d. Suppose the sample mean was 2,350 vehicles per day. Does this result support the stated population mean for this road? Consider a probability of less than 0.05 to be small. The probability that the average number of vehicles per day are more than 2,350 is ---- The result (does/does not) support the findings because this probability is (less than or equal to/ greater than) 0.05. (Type an integer or decimal rounded to four decimal places as needed.)
