This week I decided to study a population mean. I believe the population mean number of times that people bring lunch to work in a week is 2.5. I asked 15 people how many times they bring lunch vs buy lunch in a week and got the following information: 3 4 3 2 5 5 2 4 2 1 4 3 5 4 3
My Hypotheses are:
H0 : μ = 2.5
HA : μ ≠ 2.5
At the α = .05 level:
Calculate p-value.
Calculate t-stat.

I believe the population mean number of times that adults ate
fast food each week is 2.5. My data is after speaking to with 7 and
found that they ate fast food 1, 4, 0, 2, 4, 0 and 3 times last
week. I choose to test this hypothesis at .08 significance
level.
My hypothesis is: Ho: μ + = 2.5 HA : μ ≠ 2.5 n = 7
Calculate the p-value: 0.4738
Calculate the t-stat: = 0.764
Using the...

Researchers believe that male and female students at UD
differ in the population mean number of hours of sleep
that each group gets each night. Test this belief at the 10% level
of significance with the following data obtained from the Combined
Class Dataset, (and let Males be Group #1).

Mean number of desks produced per week is 42 and population
standard deviation is 4.67. the company has introduced new
production methods. A random sample of 12 weeks production
indicates 44 desks were produced each week. has the introduction of
new production methods increased average number of desks produced
each week at .05 significance level. Estimate the 95% confidence
interval

You believe that the population mean number of times that adults
go to the gym each week is less than 2.5. You spoke with 10 people
and found that they went to the gym 2, 3, 5, 3, 0, 1, 7, 3, 0, and
3 times last week. You then would choose to test this hypothesis at
the .05 significance level. Assume a random sample.

In a recent study of 53 ninth-grade students, the mean number
of hours per week that they played video games was 72. The standard
deviation of the population was 4.3. Find the 84% confidence
interval for the mean of the time playing video games.

Last week I compared 6 compound bows, this week I want to see if
the mean price for a compound bow is less than the mean price of a
crossbow. I looked at 6 manufacturers of compound bows with prices
of, 1,100, 1,000, 1,149, 999, 1100, 999. I looked at 6 different
crossbow manufacturers and they were priced, 949, 1,399, 1,499,
1,099, 999, 1,019. Test with a 0.05 significance level.
