Hello Sir/ Mam
YOUR REQUIRED ANSWER IS 0.9830
This question belong to binomial distribution where:
p | 80.00% |
n | 6 |
Now, using,
Hence,
x | P(x) |
0 | 0.0001 |
1 | 0.0015 |
2 | 0.0154 |
3 | 0.0819 |
4 | 0.2458 |
5 | 0.3932 |
6 | 0.2621 |
Now,
P(X>=3) = 0.9830
I hope this solves your doubt.

Question 4 2 pts According to the National Center for Health Statistics there is roughly an 80% chance that a person of age 20 will still be alive at age 65. Supose that 5 people of age 20 are randomly selected. What is the probability that AT LEAST 2 are alive at age 65? use the binomPdf or binomcdf function (round answer to 4 decimal places) Wk5Hw_db21
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...
Question 2 2 pts Forty percent of all registered voters in a national election are female. A random sample of 5 voters is selected. The probability that there are no females in the sample is? use the binomPdf or binomcdf function (round answer to 4 decimal places) Wk5Hw_db12
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...
Question 34 0/2 pts Question 8b 8. According to the National Center for Health Statistics, 13.7% of adults are smokers. A random sample of 300 adults is obtained. b. We want to describe the sampling distribution of the sample proportion of adults who smoke. For this question, what is the standard deviation of this sampling distribution? 0.01985 0.137 0.7614 7.218 41.1
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.
According to the National Center for Health Statistics (2009), the average height for an adult female in the United States is 63.8 inches (5 foot 3.8 inches) tall. Although the public statistics do not state a standard deviation, let's estimate the standard deviation as 2 inches. Use this information to answer the following questions. 5 pts D Question 13 What proportion of women in the United States is taller than 65 inches? DQuestion 14 5 pts What proportion of women...

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...
