Question Rachel, a city employee, would like to make the claim that the average amount that residents spend per month on public transit fare is less than $140. Rachel samples 25 city residents and obtains a sample mean of $125.80 spent per month on public transit. At the 5% significance level, should Rachel reject or fail to reject the null hypothesis given the sample data below? • Ho : µ = $140 per month; Ha : µ < $140 per month • a = 0.05 (significance level) • test statistic = -0.52 Use the graph below to select the type of test (left-, right-, or two-tailed). Then set the and the test statistic to determine the p-value. Use the results to determine whether to reject or fail to reject the null hypothesis. Alternatively, find the p-value using the table below: 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 -0.9 0.184 0.181 0.179 0.176 0.1740.171 0.1690.166 0.164 0.161 |-0.6 0.274 0.271 0.268 0.264 0.261 0.258 0.255 0.251 0.248 0.245 |-0.5 0.309 0.305 0.302 0.298 0.295 0.291…
