Question

According to the Centers for Disease Control, 33.5 % of American adults ages 20 and over suffer from hypertension. A sample of 131 adults were recruited to participate in relaxation training in hopes of lowering the incidence of hypertension. At the end of a year, the adults are re-evaluated and the proportion who suffer from hypertension is recorded.

- Completely describe the sampling distribution of the sample
proportion of adults who suffer from hypertension when samples of
size 131 are selected.
*Round any calculated values to four decimal places*.- mean: μˆpμp^ =
- standard deviation: σˆpσp^ = (round to 4 decimal places)
- np = and n(1 - p) = so the distribution of ˆpp^ is: Select an answer Not normally distributed Normally distributed

- According to the Empirical Rule, we expect 95 % of all samples
of 131 adults to result in a sample proportion between ___ and ___
with hypertension. Round your answers to 4 decimal places.
(
**Hint:**Draw the normal model based on the description in part a.)

According to the Center for Disease Control, 49.4% of American
adults 18 years old and over meet their guidelines for physical
activity. A sporting goods company claims that the proportion of
their employees who meet these guidelines is higher than the
national result. They took a random sample of 400 employees and 218
met the guidelines. Test the company’s claim using the ? = 0.05
level of significance.

The United States Centers for Disease Control and Prevention
(CDC) found that 17.9% of women ages 12 – 59 test seropositive for
HPV‑16. Suppose that Tara, an infectious disease specialist, assays
blood serum from a random sample of ?=1000 women in the United
States aged 12 – 59. Apply the central limit theorem for the
distribution of a sample proportion to find the probability that
the proportion, ?̂ , of women in Tara's sample who test positive
for HPV‑16 is...

According to a survey in a country, 39% of adults do not own a
credit card. Suppose a simple random sample of 300 adults is
obtained. Complete parts (a) through (d) below. (a) Describe the
sampling distribution of ModifyingAbove p with caret, the sample
proportion of adults who do not own a credit card. Choose the

According to the Center for Disease Control (CDC), the percent
of adults 20 years of age and over in the United States who are
overweight is 69%. One city’s council wants to know if the
proportion of overweight citizens in their city is different from
this known national proportion. They take a random sample of 150
adults 20 years of age or older in their city and find that 98 are
classified as overweight. At the 4% level of significance,...

According to a survey in a country, 27% of adults do not own a
credit card. Suppose a simple random sample of 500 adults is
obtained. Complete parts (a) through (d) below.
(a) Describe the sampling distribution of
ModifyingAbove p with caretp,
the sample proportion of adults who do not own a credit card.
Choose the phrase that best describes the shape of the sampling
distribution of
ModifyingAbove p with caretp
below.
A.Approximately normal because
n less than or equals...

According to a report on sleep deprivation by the Centers for
Disease Control and Prevention, the proportion of California
residents who reported insufficient rest or sleep during each of
the preceding 30 days is 0.081, while this proportion is 0.088 for
Oregon residents. These data are based on simple random samples of
11538 California and 4645 Oregon residents. Let p1p1 be the
proportion of California residents and p2p2 be the proportion of
Oregon residents, and report all answers to 4...

According to a survey in a country, 2727% of adults do not own
a credit card. Suppose a simple random sample of 900900 adults is
obtained. Complete parts (a) through (d) below. (a) Describe the
sampling distribution of ModifyingAbove p with caretp, the sample
proportion of adults who do not own a credit card. Choose the
phrase that best describes the shape of the sampling distribution
of ModifyingAbove p with caretp below. A. Approximately normal
because n less than or...

Check our blood pressure: In a recent study, the Centers for
Disease Control and prevention reported that diastolic blood
pressures of adult women in the United States are approximately
normally distributed with mean 80.8 and a standard deviation of
10.2.
(a) What proportion of women have blood pressures lower than
69?
(b) What proportion of women have blood pressures between 70 and
90?
(c) A diastolic blood pressure greater than 90 is classified as
hypertension (high blood pressure). What proportion...

According to a recent poll, 65% of adults who use the Internet
have paid to download music. In a random sample of size 675, adults
who use the Internet, let [^(p)] represent the sample
proportion who have paid to download music.
