These “stranded” crabs may right themselves by turning over. During a period of many days on an Atlantic Ocean beach, investigators categorized a random sample of crabs as either stranded or not stranded and additionally noted their age category. The researchers wanted to investigate whether there is convincing evidence of an association between becoming stranded and age. Data from their study are shown in the following table. Horseshoe Crab Stranded Status Young Intermediate Adult Total Yes 41 125 52 218 No 153 364 70 587 Total 194 489 122 805 If becoming stranded and age are independent in these creatures, which of the following is closest to the expected number of young stranded horseshoe crabs?
- It is commonly thought that SUVs and vans are safer than cars. If an SUV and a car are in a collision, does the SUV sustain less damage and thus need a cheaper repair? We performed 7 sample crashes of SUVs at 10mph into the rear ends of stopped cars. See the table of normal data below. SUV into car SUV damage ($) Car damage ($) CRV into Civic 1721 1274 Rav4 into corolla 1434 2327 Tucson into Forte 850 3223 Tiguan into Golf 2329 2058 Patriot into Caliber 1415 3095 Escape into Focus 1470 3386 Rogue into Sentra 2884 4560 Would you be able to say that SUVs are safer since they need less repairs?

They want to estimate how many more hours of sleep teens get if their school starts at 9:00 a.m. compared to teens whose schools start at 8:00 a.m. The district takes random samples of 50 of students from Groveland High and 39 students from Phillips High School, which starts at 9:00 a.m., and surveys them about their sleep habits. The sample mean number of hours of sleep per student at Groveland is 7.1 hours, and the standard deviation is 1.7 hours. At Phillips, the sample mean is 8.3 hours of sleep, with a standard deviation of 1.9 hours. Is it appropriate to use a two-sample t-interval for the difference in means to estimate the difference in hours of sleep for students at the two high schools? A. Yes, all the conditions for inference are met. B. No, the two samples are not independent samples. C. No, the sample sizes…A professor found out from a senior professor that engineering students in Harp University tend to do good in their Engineering Management subject, claiming that historically, the mean grade of engineering students in the said course is 1.50. Curious if this claim was true, the professor took a random sample of 9 students who took the engineering management subject. Before collecting data, he was undecided about his own claim because he knew of some students who did really good in the course but has also encountered others who did poorly. He found that their mean grade for the course is 1.35 with a standard deviation of 0.50. Use the Test of Significance Approach in testing the professor’s claim. a. Estimate population mean at 90% confidence interval. b. Between z and t, which is more appropriate to use given the data? Why? c. What are the chances that your estimate of population mean was wrong? Describe and explain a potential source of error to your estimate. d. Holding % of CI…
