Use the least squares regression line of this data set to predict a value.Meteorologists in a seaside town wanted to understand how their annual rainfallis affected by the temperature of coastal waters.For the past few years, they monitored the average temperature of coastalwaters (in Celsius), x, as well as the annual rainfall (in millimetres), y.Rainfall statistics• The mean of the x-values is 11.503.• The mean of the y-values is 366.637.• The sample standard deviation of the x-values is 4.900.• The sample standard deviation of the y-values is 44.387.• The correlation coefficient of the data set is 0.896.The least squares regression line of this data set is:y = 8.116x + 273.273How much rainfall does this line predict in a year if the average temperature of coastal watersis 15 degrees Celsius?Round your answer to the nearest integer.millimetres

Let's consider the annual precipitation levels in Los Angeles county. Suppose the average annual precipitation in LA county is normally distributed with a mean of 15 inches and a standard deviation of 3 inches. We can classify the precipitation levels in the following way: Dry Annual precipitation is more than 1 standard deviation below the mean. Normal Annual precipitation is less than 1 standard deviations below the mean and less than 2 standard deviation above the mean. Humid Annual precipitation is more than 2 standard deviations above the mean. Before answering the following questions it may be helpful to mark on a bell shaped curve where the above regions lie. According to the empirical rule, what is the probability of experiencing a Dry year in Los Angeles?

A man measures his heart rate before using a treadmill and then after walking ona treadmill for 10 minutes on 7 separate days. His mean heart rate at baseline and10 minutes after treadmill walking is 85 and 93 beats per minute (bpm), respectively.

From generation to generation, the mean age when smokers first start to smoke varies. However, the standard deviation of the age when smokers first start to smoke remains constant at around 2.1 years. The American Lung Association claims that the mean age when smokers first start to smoke is at least 17. A survey of 40 randomly selected smokers of this generation was done and it was found that the mean age when smokers first started to smoke was 18.1. Is there enough evidence to reject the claim? Describe what a Type I error is for this situation. Describe what a Type II error is for this situation.
