The average number of red blood cells per cubic mm in humans is about 5 million. We'll let μ = 5,000,000, and σ = 500,000. Give the values for the number of red blood cells for the middle 80% of people. Give the values for the number of red blood cells for the middle 60% of people. Give the 80th percentile.

c. Find the 95th percentile. (Round to three decimal places as needed.)

A research scientist reports that mice will live an average of 40 months when their diets are sharply restricted and then enriched with vitamins and proteins. Assuming that the lifetimes of such mice are normally distributed with a standard deviation of 6.3 months, find the probability that a given mouse will live i) more than 30 months;ii) less than 26 months;iii) between 35 and 47 months.   Answer all part must. answer must be correct

Find the percentile rank for each value in the data set. The data represent the values in billions of dollars of the damage of 6 hurricanes. Round to the nearest whole percentile.     2.3, 3.3, 6.2, 7.9, 9.6,11.3

The pathogen Phytophthora capsici causes bell peppers to wilt and die. Because belI peppers are an important commercial crop, this disease has undergone a great deal of agricultural research. It is thought that too much water aids the spread of the pathogen. Two fields are under study. The first step in the research project is to compare the mean soil water content for the two fields. Units are percentage of water by volume of soil. Field A samples, x: 10.0 10.7 15.5 10.4 9.9 10.0 16.6 15.1 15.2 13.8 14.1 11.4 11.5 11.0 Field B samples, x,: 8.3 8.5 8.4 7.3 8.0 7.1 13.9 12.2 13.4 11.3 12.6 12.6 12.7 12.4 11.3 12.5 A USE SALT Use a calculator to calculate x,, s,,x,, and s,. (Round your answers to four decimal places.) x, (a) Assuming the distribution of soil water content in each field is mound-shaped and symmetric, use a 5% level of significance to test the claim that field A has, on average, a higher soil water content than field B. (1) What is the level of significance?
