An оbstаcle cоurse wаs set up оn а campus and eight randomly selected students were given a chance to complete it while being timed. After that first attempt, each student sampled a new energy drink and then ran the course again. The data are shown below, assume that the variable is at least approximately normally distributed. Using a 0.05 significance level, can it be concluded that the students were faster in completing the obstacle course after sampling the energy drink? Data Table First Attempt 67 72 80 70 78 82 69 75 Second Attempt 68 70 76 65 75 78 65 68 Part 1: State the hypotheses. Enter =, , or ≠ (or you can enter NE) for the inequality. Ho: µd [ie1] [claim1]HA: µd [ie2] [claim2] Part 2: Test Statistic = [ts] (round to two decimal places) Part 3: P-value = [pv] (round to four decimal places) Part 4: State the decision about the null hypothesis, H0 (Reject or Fail to Reject). [dec] Part 5: State the conclusion. There [is] enough evidence to [rejsup] the claim that the students were faster in completing the obstacle course after sampling the energy drink.
An educаtiоnаl reseаrcher devised a wооden toy assembly project to test learning in 6-year-olds. The time in seconds to assemble the toy was recorded, the toy was dissembled, and then the child was timed a second time. The researcher would conclude that learning occurred if the mean assembly time was lower on the second attempt. Using a 0.05 significance level, can we conclude that learning did occur? Assume the variable is at least approximately normally distributed. Data Table Trial 1 100 150 150 110 130 120 118 Trial 2 90 130 150 90 105 110 120 Part 1: State the hypotheses. Enter =, , or ≠ (or you can enter NE) for the inequality. Ho: µd [ie1] [claim1]HA: µd [ie2] [claim2] Part 2: Test Statistic = [ts] (round to two decimal places) Part 3: P-value = [pv] (round to four decimal places) Part 4: State the decision about the null hypothesis, H0 (Reject or Fail to Reject).
