Question

a
random sample of 20 recent weddings in a country yielded a mean
wedding cost of $26,325.57. assume the wedding cost in this country
are normally distributed with a standard deviation of $7700.

determine a 95% confidence interval for the mean cost of all
recent weddiings in this country.

the 95% confidence interval is from $__ to $__.

Answer #1

TOPIC:Confidence interval for the population mean.

the 95% confidence interval is from $22,950.90 to $29,700.24.

A random sample of 24 observations is used to estimate the
population mean. The sample mean and the sample standard deviation
are calculated as 104.6 and 28.8,
respectively. Assume that the population is normally
distributed. Construct the 90% confidence interval for the
population mean. Then, construct the 95% confidence
interval for the population mean. Finally, use your answers to
discuss the impact of the confidence level on the width of the
interval.

1) The mean height of women in a country (ages 20-29) is 64.3
inches. A random sample of 75 women in this age group is selected.
What is the probability that the mean height for the sample is
greater than 65 inches? assume σ = 2.59
The probability that the mean height for the sample is greater
than 65 inches is __.
2) Construct the confidence interval for the population mean

Canadian couples spend an average of $25038 to cover the cost of
their weddings. Determine the cutoff of the top 10% of wedding
costs if the standard deviation is $2094 and the data is normally
distributed (USING EXCEL SOFTWARE)

In a random sample of 13 microwave ovens, the mean repair cost
was $70.00 and the standard deviation was $15.40.
Using the standard normal distribution with the appropriate
calculations for a standard deviation that is known, assume the
population is normally distributed, find the margin of error and
construct a 98% confidence interval for the population mean. A
98% confidence interval using the t-distribution was
(58.5,81.5).
Find the margin of error of the population mean.
Find the confidence interval of...

In a random sample of six mobile devices, the mean
repair cost was $60.00 and the standard deviation was $12.50.
Assume the population is normally distributed and use a
t-distribution to find the margin of error and construct a 99%
confidence interval for the population mean. Interpret the
results.
The 99% confidence interval for the population μ is (_, _)

A random sample of 91 fields of barley has a mean yield of 41.2
bushels per acre and standard deviation of 4.64 bushels per acre.
Determine the 95% confidence interval for the true mean yield.
Assume the population is normally distributed. Step 2 of 2 :
Construct the 95% confidence interval. Round your answer to one
decimal place.

In a random sample of 39 residents of the state of Florida, the
mean waste recycled per person per day was 2.1 pounds with a
standard deviation of 0.87 pounds. Determine the 95% confidence
interval for the mean waste recycled per person per day for the
population of Florida. Assume the population is normally
distributed. Step 2 of 2 : Construct the 95% confidence interval.
Round your answer to one decimal place.
