A few years ago, noon bicycle traffic past a busy section of campus had a mean of $\mu$ = 300. To see if any change in traffic has occurred, a count was taken for a sample of 19 weekdays. The sample had a mean of 340 and standard deviation of 30. Using RStudio, conduct a $\alpha$ = .05 test of H0:$\mu$ = 300, against the alternative that some change has occurred. Should we reject the null hypothesis? Based on the results of your t-test, justify your conclusion. Using RStudio, obtain a 95% confidence interval for $\mu$.
