An experiment was designed to measure how long subjects could track a moving target on a computer screen. The target moved erratically according to a predetermined program. As the experiment was designed, the first 6 subjects (volunteers recruited by signs along the main campus walkway) were tested under a control condition with no distractions, the next 12 were to be tested under a flashing light distraction, and the next 18 were to be tested under a loud noise distraction. The experiment was carried out as designed. The data (times in seconds) were as follows (listed in the sequence from first to last subject). a. Compute an ANOVA table b. Find the value of the F statistic c. What is the nominal p value for the F statistic? 5653544940 42 44 42 43 40 39 35 37 38 32 50 30 32 34 40 30 31 2927 28 2626 27 25 24 20 22 19 17 10 31 Distraction Light distraction Sound Distraction

Step-by-step explanation:

F value is 33.3792

p value is 0 so reject H0 that means the they are not statistically significant.

Step-by-step explanation:

Manufacturing job :

Mean (m) = 40,000

Standard deviation (s) = 9000

Sales job :

Mean (m) = 35000

Standard deviation (s) = 9000

Probability of earning more than 45000 if one or the other job is selected;

Obtaining the standardized scores and probability for each :

Z = (x - m) / s

P(x > 45000)

Z = (45000 - 40000) / 9000 = 0.5555

= 0.56

P(Z > 0.56) = 0.28774(Z probability calculator)

For sales :

P(x > 45000)

Z = (45000 - 35000) / 9000 = 1.1111111

= 1.11

P(Z > 1.11) = 0.1335 (Z probability calculator)

0.28774 + 0.1335 = 0.42124
