The biologist specializing in wildlife in the northern region for Problems (1) and (2) calculates the "test statistic" (Z or T test test , ) and calculates a value of 2.00

A) If the significance level is =.05 State your decision (Reject H or Fail to Reject H 0 o )

B) If the significance level is =.05 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 =.025 State your decision (Reject H or Fail to Reject H 0 o )

D) If the significance level is =.025 E) If the significance level is =.01 State your decision (Reject H or Fail to Reject H 0 o ) F) If the significance level is =.01 4) In a recent article published in Motor Trend magazine, they found that the average time for a Ford Mustang to go from 0 to 60 miles an hour is 5.4 seconds. An engineer that works at Ford Motors believes the average time for the 0 to 60 miles an hour stated in the article is too high. Note problems 5 and 6 all refer to this problem. A) State the claim in words B) State Null ( H0 ) and Alternative ( H a ) hypotheses using the correct notation. Mat-150 Chapter 8 Homework Page 3 of 5 C) State if this is a right tail, left tail or two tail tests. 5) The engineer that works at Ford Motors for problem (4) collects data for 26 Ford Mustangs and records how it takes them to go 0 to 60 miles an hour. 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 =.05 state the critical value (s) (CV. .) if you were using the traditional method of Hypothesis testing. C) If the significance level is =.025 state the critical value (s) (CV. .) if you were using the traditional method of Hypothesis testing. D) If the significance level is =.10 state the critical value (s) (CV. .) if you were using the traditional method of Hypothesis testing. 6) The engineer that works at Ford Motors for problems (4) and (5) calculates the "test statistic" (Z or T test test , ) and calculates a value of 1.51 A) If the significance level is =.05 State your decision (Reject H or Fail to Reject H 0 o ) B) If the significance level is =.05 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 =.025 State your decision (Reject H or Fail to Reject H 0 o ) D) If the significance level is =.025 Mat-150 Chapter 8 Homework Page 4 of 5 E) If the significance level is =.10 State your decision (Reject H or Fail to Reject H 0 o ) F) If the significance level is =.10 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 ( H0 ) and Alternative ( H a ) 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 =.05 state the critical value (s) (CV. .) if you were using the traditional method of Hypothesis testing. C) If the significance level is =.025 state the critical value (s) (CV. .) if you were using the traditional method of Hypothesis testing. Mat-150 Chapter 8 Homework Page 5 of 5 D) If the significance level is =.10 state the critical value (s) (CV. .) if you were using the traditional method of Hypothesis testing. 9) The tutoring supervisor at the tutoring center at the large community college (from problem 7 and 8) calculates the average grade for 105 students that regularly attend statistics tutoring and calculates the "test statistic" (Z or T test test , ) and calculates a value of 2.12 A) If the significance level is =.05 State your decision (Reject H or Fail to Reject H 0 o ) B) If the significance level is =.05 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 =.025 State your decision (Reject H or Fail to Reject H 0 o ) D) If the significance level is =.025 E) If the significance level is =.10 State your decision (Reject H or Fail to Reject H 0 o ) F) If the significance level is =.10
