Textbook Question
Chapter 14, Problem 10E
The critically endangered Maui’s dolphin is currently restricted to a relatively small stretch of coastline along the west coast of New Zealand’s North Island. The dolphins are “captured” by just collecting samples of DNA and “tagged” by identifying their DNA fingerprint. A 2010-2011 capture-recapture study “captured” and “tagged” 26 Maui’s dolphins in 2010. In 2011, 27 Maui’s dolphins were “recaptured” and through their DNA, 12 were identified as having been “tagged” in 2010. Based on these figures, estimate the population of Maui’s dolphins in 2011.

Psychologist Bernie Silverman of Michigan State University tested the effect of astrological compatibility on marriages. In studying 2,978 marriage records and 478 corresponding divorce records in Michigan, Dr. Silverman found couples whose marriges were made in horoscope heaven united and split up just as frequently as those who were not astrologically compatible. He concluded that astrological compatibility did not have an effect on marriage success.

She hypothesized that for undergraduate students, there is an association between academic majors (STEM, Business, Education, Nursing) and amount of time spent studying each week (less than 3 days, 3 to 6 days, everyday). To test her hypothesis, she randomly selected 1000 undergraduate students from various colleges/universities in Texas, and then classified each participant according to their major and amount of study time each week. For her study, she found test-statistic of 23.75 and a p-value of 0.0006. Using this information, fill in the necessary information below for her test.

- Red snapper is a rare and expensive reef fish served at upscale restaurants. A certain law prohibits restaurants from serving a cheaper, look-alike variety of fish (vermilion snapper or lane snapper) to customers who order red snapper. Researchers at a university used DNA analysis to examine fish specimens labeled "red snapper" that were purchased form vendors across the country. The DNA tests revealed that 65% of the specimens were not red snapper, but the cheaper, look-alike variety of fish.arrow_forwardThe cross-tabulation table below shows partial results from a study done at the June Mountain ski area.

To assess this issue, a consumer group investigated the tire wear on two brands of tire, A and B, say. Fifteen cars were fitted with new brand A tires and thirteen with brand B tires, the cars assigned to brand at random. (Two cars initially assigned to brand B suffered serious tire faults other than heel and toe wear, and were excluded from the study.) The cars were driven in regular driving conditions, and the mileage at which heal and toe wear could be observed was recorded on each car. For the cars with brand A tires, the mean mileage observed was 24.99 (in 10^3 miles ) and the variance was 7.75 (in 10^6 miles^2). For the cars with brand B, the corresponding statistics were 32.92 (in 10^3 miles) and 6.47(in 10^6 miles^2 ) respectively. The mileage before heal and toe wear is detectable is assumed to be Normally distributed for both brands. Part a) Calculate the pooled variance s2…arrow_forward

Federal law prohibits restaurants from serving a cheaper look-alike variety of fish (e.g. vermillion snapper or lane snapper) to customers who order red snapper. Researchers at the University of North Carolina used DNA analysis to examine fish specimens labeled “red snapper” that were purchased from vendors across the country. The DNA tests revealed that 77% of the specimens were not red snapper but the cheaper look-alike variety of fish. a. Assuming the results of the DNA analysis are valid, what is the probability that you are actually served red snapper the next time you order it at a restaurant? b. If there are five customers at a restaurant, all who have ordered red snapper, what is the probability that at least one customer is actually served red snapper?arrow_forwardIn a 2013 study, Jonason, Jones, and Lyons studied the differences in personality traits of 263 university students and compared those traits to whether the student was a "morning type" or "evening type".
