The systolic blood pressure for female diabetics between the ages of 30 and 34 has mean 131 mmHg and standard deviation = 12 mmHg.
a. Do you have enough information to compute (at least
approximately) the proportion of individuals in this population who
have blood pressure greater than 150 mmHg? If so, provide this
value. If not, explain why.
b. Do you have enough information to compute (at least
approximately) the probability that the average blood pressure in a
random sample of 80 individuals from this population will be
greater than 133 mmHg? If so, provide this value and a
justification. If not, explain why
Homework Answers
Here we have
(a)
No we don't have enough information to calculate this probability. 'We don't know anything about the shape of distribution so normal distribution can not be assumed.

Loretta, who turns 91 this year, has heard that the mean systolic blood pressure among the elderly is 115 millimeters of mercury (mmHg), but she believes that the actual value is higher. She bases her belief on a recently reported study of 22 randomly selected, elderly adults. The sample mean systolic blood pressure of the adults in the study was 120 mmHg, and the sample standard deviation was 25 mmHg. Assume that the population of systolic blood pressures of elderly...

Blood pressure in humans is a quantitative trait. Let’s assume the systolic blood pressure (top number) ranges in a population from 80 mm Hg (homozygous recessive genotype) to 220 mm Hg (homozygous dominant genotype) and is controlled by 7 unlinked genes. The alleles of each gene are additive and equal in their effects. 1. The number of additive alleles associated with the minimum (base) phenotype is ________ and the total number of phenotypes possible based solely on genetic influence is...

The following are the systolic blood pressure readings for a sample of 20 females between the ages of 40 and 80 years: 156 161 145 163 151 161 135 154 151 159 160 147 157 131 141 141 131 126 166 151. Can we conclude on the basis of these data that the population median is less than 160? Let α = .05 and find the p-value. The nature of the population distribution is completely unknown.

- Blood Pressure For women aged 18–24, systolic blood pressures (in mm Hg) are nor- mally distributed with a mean of 114.8 and a standard deviation of 13.1 (based on data from the National Health Survey). Hypertension is commonly defined as a sys- tolic blood pressure above 140. a. If a woman between the ages of 18 and 24 is randomly selected, find the probabil- ity that her systolic blood pressure is greater than 140. b. If 4 women in...

When 14 different second-year medical students measured by the systolic blood pressure of the same person, they obtained the results listed below (in mmHg). Assuming that the population standard deviation is known to be 15 mmHg, use a 0.05 significance level to test the claim that the mean blood pressure level is less than 140 mmHg. Hyper- tension is defined to be a blood pressure level that is too high because it is 140 mmHg or greater. Assume the blood...

Let us assume that it is known that the systolic blood pressure (SBP) for a particular population of individuals is approximately normally distributed with a mean of 120 mmHg with a known standard deviation of 25 mmHg. We will assume the previous to be true. Use this information to answer the following Part (a) (WebWorkiR ) An individual with a SBP of 140 or more is classified as hypertensive. What percentage of individuals in this population are hypertensive? Please submit...
