- Answer these questionThe trade volume of a stock is the number of shares traded on a given day. The data in the first accompanying table, in millions (so that 6.16 represents 6,160,000 shares traded), represent the volume of a PepsiCo stock traded for a random sample of 38 trading days in 2018.

Researchers at Allergy Institute did a study to determine the effects of washing the oil off within 5 minutes of exposure. A random sample of 1000 people with known allergies to poison ivy participated in the study. Oil from the poison ivy plant was rubbed on a patch of skin. For 500 of the subjects, it was washed off within 5 minutes. For the other 500 subjects, the oil was washed off after 5 minutes. The results are summarized in the following table.

- I need help with the part B-1 of this questionClocking the Cheetah. The cheetah (Acinonyx jubatus)isthe fastest land mammal and is highly specialized to run down prey. The cheetah often exceeds speeds of 60 mph and, according to the online document “Cheetah Conservation in Southern Africa” (Trade&Envi-ronment Database (TED) Case Studies, Vol. 8, No. 2) by J. Urbaniak, the cheetah is capable of speeds up to 72 mph. The WeissStats site contains the top speeds, in miles per hour, for a sample of 35 chee-tahs. Use the technology of your choice to do the following tasks. a. Find a 95% confidence interval for the mean top speed, μ,ofall cheetahs. Assume that the population standard deviation of top speeds is 3.2 mph. d. Comment on the advisability of using the z-interval procedure on these data.Which command can we use to generate a histogram in R? A. histogram() B. histo() C. hist() D. None of the above
