Laptop Computers and Sperm CountStudies have shown that heating the scrotum by just 1°C can reduce sperm count and sperm quality, so men concerned about fertilityare cautioned to avoid too much time in the hot tub or sauna. A new study¹ suggests that men also keep their laptop computers offtheir laps. The study measured scrotal temperature in 29 healthy male volunteers as they sat with legs together and a laptopcomputer on the lap. Temperature increase in the left scrotum over a 60-minute session is given as 2.31 ± 0.96 and a note tells us that"Temperatures are given as ° C; values are shown as mean D." The abbreviation SD stands for standard deviation. (Men who sitwith their legs together without a laptop computer do not show an increase in temperature.)¹Sheynkin, Y., et al., "Protection from scrotal hyperthermia in laptop computer users," Fertility and Sterility, February 2011; 92(2): 647-651. (a) If we assume that the distribution of thetemperature increases for the 29 men is symmetric andbell-shaped, find an interval that we expect to containabout 95% of the temperature increases.Round your answers to two decimal places.The interval istoi

It is thought that prehistoric Indians did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps. It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) for an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a given elevation. Suppose that the following data were obtained for a collection of archaeological sites in New Mexico: x 5.50 6.25 6.75 7.50 8.00 y 6 15 14 52 58 Find ȳ.
