Hi, I need help with this question.

University at Buffalo claims that the average wait time to meet with counseling services 15 days. A random survey of 75 students currently waiting for services revealed that the average wait time is 17.9 days with a standard deviation of 6.7 days. Conduct a hypothesis to test the state UB's claim. What type oftest should be run? ttest of a mean 0 Z-test for a mean 0 t-test for a proportion O z-test of a proportion The alternative hypothesis indicates a O left-tailed test 0 righttailed test two-tailed test Calculate the p-value (rounded to at least 4 decimal places) 0.0002 s
