I have 9 statistic problems that need to be answered. Can someone please provide answers with explanations? Attached is a word document of problems.

1. . In a binomial situation n _ 5 and _ _ .40. Determine the probabilities of the following
events using the binomial formula.
a. x _ 1
b. x _ 2


2. A normal population has a mean of 80.0 and a standard deviation of 14.0.
a. Compute the probability of a value between 75.0 and 90.0.
b. Compute the probability of a value 75.0 or less.
c. Compute the probability of a value between 55.0 and 70.0.

3. A recent study by the Greater Los Angeles Taxi Drivers Association showed that the mean
fare charged for service from Hermosa Beach to the Los Angeles International Airport is $18.00 and the standard deviation is $3.50. We select a sample of 15 fares.
a. What is the likelihood that the sample mean is between $17.00 and $20.00?
b. What must you assume to make the above calculation?

4. Furniture Land South surveyed 600 consumers and found that 414 were enthusiastic about a new home décor they plan to show in their store in High Point, North Carolina. Construct the 99 percent confidence interval for the population proportion.


5. Research at the University of Toledo indicates that 50 percent of the students change their
major area of study after their first year in a program. A random sample of 100 students in
the College of Business revealed that 48 had changed their major area of study after their
first year of the program. Has there been a significant decrease in the proportion of students
who change their major after the first year in this program? Test at the .05 level of significance.


6. The liquid chlorine added to swimming pools to combat algae has a relatively short shelf life before it loses its effectiveness. Records indicate that the mean shelf life of a 5-gallon jug of chlorine is 2,160 hours (90 days). As an experiment, Holdlonger was added to the chlorine to find whether it would increase the shelf life. A sample of nine jugs of chlorine had these shelf lives (in hours):
2,159 2,170 2,180 2,179 2,160 2,167 2,171 2,181 2,185
At the .025 level, has Holdlonger increased the shelf life of the chlorine? Estimate the pvalue.


7. The null and alternate hypotheses are:
H0: _1 _ _2
H1: _1 _ _2
A random sample of 15 observations from the first population revealed a sample mean of 350 and a sample standard deviation of 12. A random sample of 17 observations from the second population revealed a sample mean of 342 and a sample standard deviation of 15. At the .10 significance level, is there a difference in the population means?
Note: Use the five-step hypothesis testing procedure for the following exercises.

8. Clark Heter is an industrial engineer at Lyons Products. He would like to determine whether there are more units produced on the afternoon shift than on the day shift. A sample of 54 day-shift workers showed that the mean number of units produced was 345, with a standard deviation of 21. A sample of 60 afternoon-shift workers showed that the mean number of units produced was 351, with a standard deviation of 28 units. At the .05 significance level, is the number of units produced on the afternoon shift larger?

9. Two boats, the Prada (Italy) and the Oracle (U.S.A.), are competing for a spot in the upcoming America’s Cup race. They race over a part of the course several times. Below are the sample times in minutes. At the .05 significance level, can we conclude that there is a difference in their mean times?
Boat Times (minutes)
Prada (Italy) 12.9 12.5 11.0 13.3 11.2 11.4 11.6 12.3 14.2 11.3
Oracle (U.S.A.) 14.1 14.1 14.2 17.4 15.8 16.7 16.1 13.3 13.4 13.6 10.8 19.0
