A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 22.0 pounds and a standard deviation of 5.4 pounds.

Step 1 of 2:

If a sampling distribution is created using samples of the amounts of weight lost by 77 people on this diet, what would be the mean of the sampling distribution of sample means? Round to two decimal places, if necessary.

A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 23.6 pounds and a standard deviation of 7.0 pounds. Step 1 of 2 : If a sampling distribution is created using samples of the amounts of weight lost by 61 people on this diet, what would be the mean of the sampling distribution of sample means? Round to two decimal places, if necessary.

Two Earth satellites, A and B, each of mass mmm = 930 kgkg , are launched into circular orbits around the Earth's center. Satellite A orbits at an altitude of 4000 kmkm , and satellite B orbits at an altitude of 12600 kmkm
What are the potential energies of the two satellites? (in Jules)
What are the kinetic energies of the two satellites?     (in Jules)
How much work would it require to change the orbit of satellite A to match that of satellite B? (in jules)
hint this is tricky problem

You are given the following information with respect to a bond:

par amount: 1000 / term to maturity 3 years / annual coupon rate 6% payable annually

You are also given that the one, two, and three year annual spot interest rates are 7%, 8%, and 9% respectively.

1). Calculate the value of the bond.

2). Calculate the annual effective yield rate for the bond if the bond is sold at a price equal to its value.

The yield to maturity (YTM) on 1-year zero-coupon bonds is 7% and the YTM on 2-year zeros is 8%. The yield to maturity on 2-year-maturity coupon bonds with coupon rates of 11% (paid annually) is 7.7%.

                  Pre-program: 59, 61, 47, 60, 35, 80

                  Post-program: 71, 75, 55, 62, 50, 87

c) Phizex explored the effects of two treatments for baldness to see if either drug resulted in greater hair

growth than the control group. (α = 0.05)

                  Drug2: 10,   13,   15,   8,   11,   9

                  Control: 8,   7,   8,   11,   9,   7

A stadium manager is interested in whether the fans that buy tickets are demographically the same as the general population of the city. Currently 42% are Caucasian, 35% are Hispanic, 12% are African American, 8% are Asian, and the rest are defined as other.

Is there an association between a college student’s level of drinking alcohol (classified as none, some, or considerable) and her/his residence situation (classified as living on-campus, off-campus with parents, or off-campus but not with parents)?

A researcher used data from the American Time Use Survey (ATUS) to investigate whether high school math teachers spend more time working per day than high school history teachers.

Is the percentage of all males who watch Walking Dead at COC larger than that of females?

Researchers are trying to determine if the Atkins diet was effective by measuring adult’s BMI before the diet, and then after being on the diet for 3 weeks.

For each of the following research questions match the appropriate statistical inference procedure for investigating the question. Answers may be used more than once.

Bon Air Elementary School has 1000 students. The principal of the school thinks that the average IQ of students at Bon Air is at least 110.

Answers: Chi Square Goodness of Fit (GOF)            Chi-square procedures for two-way tables            ANOVA procedures            Two-sample t-procedures for comparing means            One-sample t-procedures for a mean            Two-sample z-procedures for comparing proportions            One-sample z-procedures for a proportion            Paired-sample t-procedures      

For the variable continues to be assigned by gender (men and women) it generates the
two-means hypothesis test to compare whether there is a difference between the mean of variable X of the Woman
and the mean of variable X for Men; and the hypothesis test of two variances
(standard deviation) to determine whether there is a difference between the standard deviation of the
variable X for Women and the standard deviation of variable X for Men

The claim that will use for both the mean and standard deviation parameter is "greater than"
Use a 95% confidence level (=0.05).

The SAT is a standardized college admissions test used in the United States. The following two multi-part questions will ask you some questions about SAT testing.

This is a 6-part question asking you to determine some probabilities of what happens when a student guessed for all of their answers on the SAT. Use the information below to inform your answers for the following questions.

An old version of the SAT college had a -0.25 point penalty for every incorrect answer and awarded 1 point for a correct answer. The quantitative test consisted of 44 multiple-choice questions each with 5 answer choices. Suppose a student chooses answers by guessing for all questions on the test.

1. What is the standard error of guessing on all 44 questions? Use the Central Limit Theorem to determine the probability that a guessing student scores 8 points or higher on the test.
