Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.

Question

Q2:
A survey in the N.Y. Times Almanac finds the mean
commute time (one way) is 25.4 minutes for the 15
largest US cities. The Austin, TX chamber of
commerce feels that Austin's commute time is less and
wants to publicize this fact. The mean for 25 randomly
selected commuters is 22.1 minutes with a standard
deviation of 5.3 minutes. At the a = 0.10 level, is the
Austin, TX commute significantly less than the mean
commute time for the 15 largest US cities?

A company that supplies LP gas for heating keeps data on the low temperature for each day of each month. It sum-marizes these data by finding the mean, median, standard deviation and interquartile range. The company assumesthat people use the LP gas for heat when the temperature is below 70°, so it creates a second set of data by subtract-ing 70 from each daily low temperature. Which of the four summary statistics will change for this second data set?A) mean and median onlyB) mean and standard deviation onlyC) median and IQR onlyD) standard deviation and IQR onlyE) mean, median, standard deviation, and IQR

The University of Georgia has several football players participating in the NFL draft this season. A few former coaches are helping the players prepare for the NFL tryout by tracking their practice performance. One coach calculates the athlete's speed in feet per second each round and then finds the mean and standard deviation for all rounds. Since the workout tested at the NFL tryout is the 40 yard dash, the coach decides to convert these speeds to yards per second instead of feet per second, where 1 yard is equal to 3 feet. Which of the following best describes what would happen to the summary statistics for the athletes? (A) The mean would increase, but the standard deviation would remain the same. (B) Both the mean and standard deviation would remain the same. (C) Both the mean and standard deviation would decrease. (D) The mean would decrease, but the standard deviation would remain the same. (E) The mean would decrease, but the standard deviation would increase.
A business school dean in Ohio wants to know if graduates who completed an internship during their undergraduate years earn more than business undergraduates who do not complete an internship while in college. Based on national survey from 1,500 business alumni with less than six years of work experience, they earn on average $50,970 with a standard deviation of $12,976. Business alumni from the Ohio school who completed internships on average earned $53,497. The dean wants you to be 96% confident in your results. a. State in statistical terms the null and alternative hypotheses. b. Determine the appropriate test statistic (z or t). c. Determine the critical value(s). d. Compute the test statistic. e. Make a decision on the hypotheses. (which hypothesis is correct?) f. Determine the p-value for the test statistic.
