The average weight of a sample of 36 bags of oat cookies is 35
ounces. The population standard deviation is 4 ounces, a 95%
confidence interval will be: Select one: a. 35 ± (1.33) b. 35 ±
(1.31) c. 35 ± (1.35) d. 35 ± (1.32)

A sample of 21 boxes of “Chocolate Crème Covered Coconut
Crispy Chip Co-Co Cookies” showed a mean of 23.5 ounces and a
standard deviation of 1.1 ounces. Check the hypothesis claim that
boxes have the proper weight of 24 ounces. Use α= 0.10
significance; for the original claim H0: μ = 24 and H1: μ <
24.
t (statistic) =_ _
t (critical) = __________
Reject or fail to reject H0? _______

A random sample of 15 students showed that their average fear of
math was 84.8 on a 1-100 scale, with a standard deviation of 2.7.
At the α = .01 significance level, test the claim that the average
fear of math of all students is below 85 on this scale. b) Suppose
now the same mean and standard deviation were found in a random
sample of 10000 students. Again, at the α = .01 significance level,
test the claim that...

A simple random sample of size nequals 40 is drawn from a
population. The sample mean is found to be 110.6 , and the sample
standard deviation is found to be 23.3 . Is the population mean
greater than 100 at the alpha equals0.01 level of
significance?
Determine the null and alternative hypotheses.
Compute the test statistic.(Round to two decimal places as
needed.)
Determine the P-value.
What is the result of the hypothesis test?
the null hypothesis because the P-value...

HT Mean: A Packaging Company produces boxes out of cardboard and
has a specified weight of 35 oz. It is known that the weight of a
box is normally distributed with standard deviation 1.3 oz. A
random sample of 36 boxes yielded a sample mean of 35.5 oz. At 5%
level of significance, test the claim that the mean weight of a box
is 35 oz or is there significant evidence that the mean weight is
greater than 35 oz....

9.2.13 A random sample of 35 SEC Division I football defensive
lineman have an average weight of 359.133 pounds with a standard
deviation of 33.436 pounds. A random sample of 32 Big 12 Division I
defensive lineman have an average weight of 357.467 pounds with a
standard deviation of 33.084 pounds.
a. Construct a 90% confidence interval for the difference
between the average weight of a football defensive lineman in the
SEC versus the Big 12.
b. Are Division I...
