The compressive strength of concrete is being tested by a civil engineer. She tests 14 specimens and obtains the following data (in psi): 2219 2248 2241 2228 2276 2287 2245 2247 2245 2297 2272 2246 2270 2263 Assuming that the compressive strength is normally distributed, test the hypothesis that the mean strength is at least 2249 psi. Report your P-value and use a 95% confidence level to draw your conclusion. P-value .1296 (a) Cannot Reject (b) Reject Now assume that the compressive strength is not normally distributed, and test the hypothesis that the median strength is greater than 2254 psi. Report your P-value and use a 95% confidence level to draw your conclusion. Hint: if the median is 2254 psi, then you can count how many of the samples have strengths above and below that value. And if you view the data as being either above or below the median, you can calculate the related P-value. P-value number (rtol
