Question

1. After the last frost, 189 apples were picked randomly and 43
were found to be not fit for sale.

a. Construct a 95% confidence interval for the population
proportion of unsaleable apples.

b. How large a sample should be taken to estimate the proportion of
unsaleable apples to

within 2% of population proportion, using:

i:p*=43/189 ii. P*=1/2 ?

Answer #1

Announcements for 84 upcoming engineering conferences were
randomly picked from a stack of IEEE Spectrum magazines. The mean
length of the conferences was 3.94 days, with a standard deviation
of 1.28 days. Assume the underlying population is normal.
A. What is the error bound of 95% confidence interval for the
population mean length of engineering conferences? (Round to 3
decimal places)
B. Construct a 95% confidence interval for the population mean
length of engineering conferences.
What is the lower bound?...

1. Construct a 95% confidence interval for the proportion of
defective items in a process when it is found that a random sample
of 100 items contains 6 defectives.
2. How large a sample is needed in problem 1 above to estimate
the proportion of defective items to within 2% with 95%
confidence?

In a study of 1314 randomly selected medical malpractice
lawsuits, it was found that 1023 were dropped or dismissed.
?) Construct a 95% confidence interval for the
proportion of all medical malpractice lawsuits that are dropped or
dismissed.
?) It is claimed that the true proportion of
all medical malpractice lawsuits that are dropped or dismissed is
0.80.
Does your result from part ? support this
claim?

thicknesses of all linoleum tiles in this factory. Round your
answers to two decimal places.

In a survey of 1037 adults from the US age 65 and
over,643 were concern about getting flu.
a) Find a point estimate for the population proportion P of
those concerned about getting the flu.
b) Construct a 95% confidence interval for the population
proportion. What does this interval say to you?
c) Find the minimum sample size needed to estimate the
population proportion at the 99% confidence level in order to
ensure that the estimate is accurate within 4%...

A sample of 113 hypertensive people were given an
anti-hypertensive drug, and the drug was found to be effective in
66 of those people. (By effective, we mean that their diastolic
blood pressure is lowered by at least 10 mm Hg as judged from a
repeat measurement taken 1 month after taking the drug.)
a) Find a 94% confidence interval for the true proportion of the
sampled population for which the drug is effective.
b) Using the results from the...

A research agency conducted a survey on randomly selected 2000 Malaysian adults aged 18 and over regarding weight issue. These adults were asked if they want to lose weight and 63% said yes.
