The U.S. National Center for Health Statistics reports that 60% of those with artificial hip and knee joints are female; If 30 of these people are selected at random, find the probability that fewer than 15 are female.
Homework Answers
We will use Binomial distribution with n=30 and p=0.60
P(Fever than 15 Females) =P(X<15)=P(X<=14)
We will use Excel function ''=BINOMDIST(14,30,0.6,TRUE)'' it will give probability 0.09705
P(P(Fever than 15 Females) =P(X<15)=0.0971 (in Four Decimal)
Hope this will be helpful. Thanks and God Bless You:)

The National Center for Health Statistics reports that 25% of all Americans between the ages of 65 and 74 have a chronic heart condition. Suppose you live in a state where the environment is conducive to good health and low stress and you believe the conditions in your state promote healthy hearts. To investigate this theory, you conduct a random telephone survey of 18 persons 65 to 74 years of age in your state. "(Round your answer to 2 decimal...

8.9 According to the National Center for Health Statistics, as of 2012, it is estimated that 24% of adults in Missouri smoke. You wish to know the probability of selecting from this popula- tion a random sample of 30 people containing 8 or fewer smokers a. Use a statistical program to determine the exact probability of getting 8 or fewer smok- ers. (Hint: refer to section 5.4.) b. Now use the normal approximation of the binomial distribution to answer the...

The National Center for Health Statistics estimates that 16.9 percent of U.S. children and adolescents aged 2 to 19 were obese in 2009-2010. Assume that this obesity rate holds true today. If you were to randomly select 18 U.S. children or adolescents, find each of the following: Notei: carry at least 6 digit precision for any intermediate calculations then round your answer to 4 decimal places Note2: Any value that is less than 0.0001, (1 x 10-), can be rounded...

The National Center for Health Statistics, housed within the U.S. Centers for Disease Control and Prevention (CDC), tracks the number of adults in the United States who have health insurance. According to this agency, the uninsured rates for Americans in 2018 are as follows: 5.1% of those under the age of 18, 12.4% of those ages 18–64, and 1.1% of those 65 and older do not have health insurance (CDC website). Approximately 22.8% of Americans are under age 18, and...

1. The National Center for Health Statistics reports that the systolic blood pressure for males 35 to 44 years of age has a mean of 128. In a study of business executives, a random sample of 101 executives has a mean systolic blood pressure of 134 with a standard deviation of 25. Do the data suggest that the mean systolic blood pressure for business executives is higher than 128? Use a 5% significance level?

Fill in the Blanks The National Center for Education Statistics reports that mean scores on the standardized math test for eighth-graders in 2009 increased slightly from those for previous years. The mean score in 2009 was 283. Assume that the standard deviation is 10. Find the probability that the test score of a randomly selected eighth-grader was greater than 290 What proportion of test scores was between 295 and 300? Suppose students who scored at the 5th percentile or lower...

Adult diabetes: A National Center for Health Statistics data brief states that in 2013 9% of US. adults aged 18 and over have diagnosed diabetes. Suppose that this year, we select a random sample of 100 adults. The conditions are not met for use of a normal model since the expected number of adults with diagnosed diabetes is only 9 (9% of 100). Therefore, we ran a simulation withp = 0.09. Suppose that the sample has 15 adults (or 15%)...

The National Center for Health Statistics reports that the mean systolic blood pressure for males 35 to 44 years of age is 128 mmHg and the standard deviation in this population is 15 mmHg. The medical director of a large company looks at the medical records of 72 executives in this age group and finds that the mean systolic blood pressure in this sample is x 126.07 mmHg. Find the power of a one sided test that the executives blood...
