Test whether he given claim is supported or not supported using a 0.05 significance level. Assume that the sample has been randomly selected from a population with a normal distribution.

A fast food outlet claims that the mean waiting time in line is less than 3.7 minutes. A random sample of 20 customers has a mean of 3.5 minutes with a standard deviation of 0.8 minute. Use a significance level of 0.05 to test whether the fast food outlet's claim is supported or not supported.
