ou would like to get the highest paying job possible after graduating from UCR and are currently deciding vhether to enroll in ECON 108 in the fall term or not. You find a sample of recent UCR graduates that majc n Economics (there are no double majors in the samples). You sampled 100 Economics majors that took ECON 108 and you find that the average starting salary is 72K dollars, with a sample standard deviation of 10K dollars. You sampled 75 Economics majors that did not take ECON 108 and you find that the average starting salary is 65K dollars, with a sample standard deviation of 15K dollars. Which of the following statements is most correct? O I am not very confident in the results of my hypothesis test because the range in which I fail to reject the null hypothesis is relatively large.

The average expenditure on Valentine's Day was expected to be $100.89 (USA Today, February 13, 2006). Do male and female consumers differ in the amounts they spend? The average expenditure in a sample survey of 44 male consumers was $137.38, and the average expenditure in a sample survey of 35 female consumers was $65.11. Based on past surveys, the standard deviation for male consumers is assumed to be $35, and the standard deviation for female consumers is assumed to be $12. The z value is 2.576. Round your answers to decimal places. b. At 99% confidence, what is the margin of error? c. Develop a 99% confidence interval for the difference between the two population means.

Question: In a survey of buying habits, 400 women shoppers are chosen at random in super market 'A' located in a certain section of the city. Their average weekly food expenditure is dollar 250 with a standard deviation of Dollar 40. For 400 women shoppers chosen at random in super market 'B' in another section of the city, the average weekly food expenditure is Dollar 220 with a standard deviation of Dollar 55. Test at 1% level of significance whether the average weekly food expenditure of the two populations of shoppers are equal.

Sumo wrestlers have 15 matches per tournament and the benefits of winning 8 matches (a winning record) are very large, compared to the benefits of winning a 5 matches (compared to 4) or the benefit of winning 10 matches (compared to 9). Sumo wrestlers who have won 7 matches and lost 7 matches tend to win a statistically anomalous (they win too often) amount of the time in their last match of the tournament. In order to show that this is unlikely to be explained by 'wrestlers with 7-7 record try hard to win' researchers show that wrestlers who win an 8th match in these circumstances then tend to lose a statistically anomalous amount of the time when they next face that same opponent (they lose too frequently when those wrestlers next meet). This result is consistent with 'win trading'. The researchers find that wrestlers about to retire benefit less from the 'wrestlers at 7-7 tend to win' effect. Pick the answer which best explains the fact that wrestlers tend to win an 8th match more…
