Chapter 8 Homework E) If the significance level is a =.10 State your decision (Reject H, or Fail to Reject H. ) F) If the significance level is a =.10 write your statement 7) The tutoring center at a large community college states that the average grade of a student that regularly attends statistics tutoring is at least an 85. Note problems 8 and 9 refer to this problem. A) State the claim in words B) State Null (H. ) and Alternative (H. ) hypotheses using the correct notation. C) State if this is a right tail, left tail or two tail tests. 8) The tutoring supervisor at the tutoring center at the large community college (from problem 7) collects the data for 105 students that regularly attend statistics tutoring and records their grades. A) What table should you use to obtain the critical value (s) if you were using the traditional method of Hypothesis testing. B) If the significance level is a =.05 state the critical value (s) (C.V.) if you were using the traditional method of Hypothesis testing. C) If the significance level is a =.025 state the critical value (s) (C.V.) if you were using the traditional method of Hypothesis testing.

B) If the significance level is a =.05 write your statement Hint: it should be one of these four: "enough sample data to reject the claim", "NOT enough sample data to reject the claim", "enough sample data to support the claim" or "NOT enough sample data to support the claim" C) If the significance level is o =.025 State your decision (Reject H. or Fail to Reject H. ) D) If the significance level is o =.025 write your statement E) If the significance level is o =.10 State your decision (Reject H, or Fail to Reject H. ) F) If the significance level is o =.10 write your statement Page 5 of 5
