Rain that diluted the salt occurs about 10% of the time, while the non salty outgoing tides occurs twice per day. You take your dog for a walk down by the river at random during the weekend and notice that he'll drink from the river 30% of the time when the salt is sufficiently low. Question somebody else points that it's more likely to rain in the afternoon. You happen to be the time of year when half the tides are also occurring in the afternoon ( the others occur roughly 12 hours later during the night) if the probability of rain during this outgoing tide period increases to 15 % what is the probability of there being an afternoon tide during a rain ?I need part C Thankyou

A pharmaceutical company conducts a clinical trial on people with high levels of LDL cholesterol. The trial involves a random sample of n = 16 persons who have high levels of LDL. Each person has their LDL level measured prior to the beginning of the drug trial. Each person is then to take a new drug that is believed to lower ones LDL levels. After a period of 4-weeks, the LDL level of each person is measured again. The difference between the initial LDL level and the LDL-level four weeks after taking the drug is then computed. -0.56, -0.07,-0.2, -0.42, -0.32, -0.99, -0.26, -0.32, -0.73, -0.51, -0.59, -0.62, -0.78, -0.04, -0.5, 0.13 Data from the sample, are saved in the Download.csv file. Assuming the difference in the LDL-levels is Normally distributed, find a 97% confidence interval for μ, the mean difference in the LDL-level of a person after taking the drug for four weeks.

- Allergic reactions to poison ivy can be miserable. Plant oils cause the reaction. 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.
