A botanist wishes to estimate the typical number of seeds for a
certain fruit. She samples 49 specimens and counts the number of
seeds in each. Use her sample results (mean = 68.6, standard
deviation = 14.2) to find the 80% confidence interval for the
number of seeds for the species. Enter your answer as an
open-interval (i.e., parentheses)
accurate to 3 decimal places.

Expert Solution
Solution :
It is given that a botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 49 specimens and counts the number of seeds in each. We have to use her sample results (mean = 68.6, standard deviation = 14.2) to find the 80% confidence interval for the number of seeds for the species.
Let 
be the mean number
of seeds for the species.
We know that the 100 (1
)% Confidence
Interval for Population Mean () is given as
,
Thus , the data that we have from the given information are ,
Thus , the 80% Confidence Interval for Population Mean
() is given as
,

A botanist wishes to estimate the typical number of seeds for a
certain fruit. She samples 36 specimens and counts the number of
seeds in each. Use her sample results (mean = 76.3, standard
deviation = 10.8) to find the 99% confidence interval for the
number of seeds for the species. Enter your answer as an
open-interval (i.e., parentheses)
accurate to 1 decimal place.

A botanist wishes to estimate the typical number of seeds for a
certain fruit. She samples 64 specimens and counts the number of
seeds in each. Use her sample results (mean = 73.2, standard
deviation = 13.2) to find the 80% confidence interval for the
number of seeds for the species. Enter your answer as an
open-interval (i.e., parentheses)
accurate to one decimal place (because the sample statistics are
reported accurate to one decimal place).

A botanist wishes to estimate the typical number of seeds for a
certain fruit. She samples 60 specimens and counts the number of
seeds in each. Use her sample results (mean = 67.4, standard
deviation = 16.8) to find the 95% confidence interval for the
number of seeds for the species. Enter your answer as an

A certain airline wishes to estimate the mean number of seats
that are empty on flights that use 737-airplanes. There are 189189
seats on a 737. To do so, the airline randomly picks n=34n=34
flights. For each flight, the number of empty seats is counted. The
data are given below.
46, 40, 58, 59, 44, 46, 51, 47, 37, 49, 49, 50, 44, 42, 47, 49, 46,

Q: An agronomist wanted to estimate the mean
weight of a certain fruit (?) in his farm. He selected a random
sample of size ? = 16, and found that the sample mean ?̅ = 55 gm
and a sample stranded deviation ? = 3 gm. It is assumed that the
population is normal with unknown standard deviation (?).
a) Find a point estimate for (?).
b) Find a 95% confidence interval for the population mean
(?).

. A chemist wishes to detect an impurity in a
certain compound that she is making. There is a test that detects
an impurity with probability 0.92; however,
This test indicates that an impurity is there when it is not
about 5% of the time. The chemist produces compounds with the
impurity about 15% of the time. A compound is selected at random
from the chemist’s output. The test indicates that an impurity is
present. What is the conditional probability...

A airline wishes to estimate the mean number of seats
that are empty on flights that use 737-airplanes. There
are 189 seats on a plane. To do so, the airline
randomly picks n=35 flights. For each flight, the number of empty
seats is counted. The data are given below.

1. A researcher wishes to estimate the proportion of
left-handers among a certain population. In a random sample of 900
people from the population, 74% are left-handed.
a. Find the margin of error for the 95% confidence interval for
the population proportion of the left-handers.
b. Find the 95% confidence interval for the population
proportion of the left-handers to four decimal places.

A survey asked orchestra members to estimate the number of hours
they practice on a typical day. From the results, it was determined
that 25 pianists reported practicing an average of 4.1 hours a day
with a standard deviation of 0.77, while 31 percussionists reported
practicing an average of 3.7 hours a day with a standard deviation
of 1.03. Using alpha = 0.05, test the claim that pianists practice
longer than percussionists.
