Total Cholesterol According to the U.S. Center for Disease Control (CDC), the mean total cholesterol for men between the ages of 20 and 29 is 180 micrograms per decilitre with a standard deviation of 36.2. A healthy total cholesterol level is less than 200, 200–240 is borderline, and above 240 is dangerous. Assume that the distribution is approximately Normal.
a. For a randomly selected man from this group, what is the probability that his total cholesterol level is 200 or more? |

Assume total cholesterol levels (TChol) are normally distributed with mean μ = 215 mg/dl and standard deviation σ = 30 mg/dl for the adult American population. That is, TChol ~ N(215, 302). Total cholesterol values of 240 mg/dl or greater are considered high; and levels in the range of 200 to 240 are called borderline high. a. What proportion of this population do we expect to find with high cholesterol? What proportion do we expect to find with borderline high...
the cholesterol level of men in the united states are normally distributed, with a mean = 215 milligrams per deciliter and a standard deviation = 25 milligrams per deciliter. if a man is randomly selected, what is the probability that his cholesterol level is more than 245? based on your answer to #1, would you consider it unusual for a man to have a cholesterol level of 245? Why? what cholesterol level cuts off the lower 10% of levels
According to the Center for Disease Control (CDC), about 1 in 88 children in the United States have been diagnosed with autism. a. In your study, you are randomly selecting a group of 24 children from the population of school-aged children in your area. Your random variable is the number of children in your sample with autism. Explain why you can use the binomial probability distribution to determine the probabilities of possible number of children in your study having autism...
A study is run to estimate the mean total cholesterol level in children 2-6 years of age. A sample of 13 participants is selected and their total cholesterol levels are measured as follows. 170 185 225 240 196 175 180 194 147 223 240 220 210 a) Assume the mean total cholesterol level is 190 in children 2-6 years of age at national level. Test whether the cholesterol level in this sample is significantly different from national level. b) Generate...
Assume total cholesterol value for a certain population is approximately bell shaped with a mean of 200 mg/100 ml and a standard deviation of 20 mg/100ml. What is the proportion that an individual picked at random from this population will have a cholesterol level between 200 mg/100 ml and 240 mg/100 ml? a. 47.7% b. 53.5% c. 50%
Problem B: Cholesterol is a fatty substance that is an important part of the outer lining (membrane) of cells in the body of animals. Its normal range for an adult is 120-240 mg/dl. The Food and Nutrition Institute of the Philippines found that the cholesterol level for Filipino adult has a mean of 159.2 mg/dl and 83.4% of adults have a cholesterol level below 200 mg/dl. Suppose that the cholesterol level is normally distributed. e) An adult is thought to be at...
Assume men's heights are normally distributed with mean 69.5 in. and standard deviation 2.4 in. If you randomly selected a man whats the probability that his height would be A. Over 6 feet B. Between 5'9 and 6'4 C. Less than 2 standard deviations above the mean D.What is height that separates the tallest 10% of men from the rest of men? What do we call this value? E. If 25 men were randomly selected what is the probability that...
1.) Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 42 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6,846 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 6,846 lb/42=164 What is...
