The mean winter temperature in San Francisco for the month of December is 49°F. Suppose a random sample of 15 days in December showed a samp mean of 45.7°F. Assume that o = 3 and a normally distributed population. Test whether the population mean temperature is less than 49°F, using level significance a = 0.05. Select one: O a. O b. O c. O d. p-value = 0.0100, reject Ho. p-value = 0.9999, do not reject Ho. p-value = 0.00001, reject Ho. p-value = 0.1357, do not reject Ho.
