6. A Little League baseball coach wants to know if his team is representative of other teams in scoring runs. Nationally, the average number of runs scored by a Little League team in a game is 7.8. He chooses nine games at random in which his team scored 7, 8, 5, 9, 4, 11, 9, 8, and 8 runs. Is it likely that his team's scores is different from the national distribution? Assume an alpha level of 0.10. i) Since sample mean and standard deviation not given, we use the above data and calculator to find x = ii) use a 1% level of significance to test the claim that the population average catch per day is now different than 7.8. and s =_ a. Write Null and alternate hypotheses. b. Find Sample Test Statistics (write formula and round your answer to two decimal places) c. Find P-value and compare with a (round your answer to four decimal places) d. Do you reject or fail to reject Ho e. Write a good conclusion in the context of the application g. Write the possible error 7. To test the claim H1 : o
