We are interested in conducting a study to determine whether a study intervention significantly improves college students’ test scores. The population’s GPA m = 2.64 and s = 0.42. We hope that intervention will improve girls’ body esteem scores by 0.25 points. We plan to recruit a sample of 36 students. We set our alpha level at .05 for two-tailed test. Determine the statistical power that this proposed study would have; report your answer as a percentage.

8. Assume that male and female births are equally likely and that the birth of any child does not affect the probability of the gender of any other children. Suppose that 650 couples each have a baby; find the mean and standard deviation for the number of girls in the 650 babies.

9.A sales firm receives an average of four calls per hour on its toll-free number. For any given hour, find the probability that it will receive exactly five calls. Use the Poisson distribution.

Assume that different groups of couples use a particular method of gender selection and each couple gives birth to one baby. This method is designed to increase the likelihood that each baby will be a​ girl, but assume that the method has no​ effect, so the probability of a girl is 0.5. Assume that the groups consist of 41 couples. Complete parts​ (a) through​ (c) below. a. Find the mean and the standard deviation for the numbers of girls in groups of 41 births. The value of the mean is muequals nothing. ​(Type an integer or a decimal. Do not​ round.)

It is claimed that if parents use the UCHOOS method of gender selection there is a greater than 50% chance of have a girl. Determine the true proportion using a 95% confidence. Assume the sample data consist of 56 girls born in 105 births. A random sample of 19 green M&Ms has a mean of .8635 grams and a standard deviation of .057 grams. Test the claim that the mean weight of all green M&Ms is different than .8535 grams. Assume an alpha value of .05.

9.

You and your spouse just adopted twin girls, little Heather and Beth. You want to make sure they

are taken care of for the next 22 years. (A)Based on the following information, how much life

insurance needs to be purchased for the husband, if any? (B) How much, if any, needs to be

purchased for the wife? Assume 3% inflation rate.

Market Labor Value

Husband: $72,000

Wife: $15,000

Household Production Value

Husband: $15,000

Wife: $40,000

Here are summary statistics for randomly selected weights of newborn​ girls: nequals193​, x overbarequals32.2 ​hg, sequals6.4 hg. Construct a confidence interval estimate of the mean. Use a 90​% confidence level. Are these results very different from the confidence interval 31.1 hgless thanmuless than33.1 hg with only 15 sample​ values, x overbarequals32.1 ​hg, and sequals2.1 ​hg?

What is the confidence interval for the population mean mμ​?

Are the results between the two confidence intervals very​ different?

The pornography industry is one of the most lucrative in the nation— some estimates are that it grosses more than $4 billion annually—however the women and girls who work in this industry see very little of that money. Prostitution as well is highly profitable for a growing number of pimps and human traffickers selling both women and children. What are the legal and moral differences between these two types of sex work, and how have changing social norms contributed to the legal status of both today?

Discuss police in schools, including an example of a school-based program with a school and police partnership. Explain your view of police officers in schools.

Suppose that the probability that any random student graduates with honors is 0.05. Also, we know that the probability of a student that graduated with honors, getting into graduate school is 0.80. The probability that a student that did not graduate with honors gets into graduate school is 0.10. TRUE or FALSE: Given that a random student got into graduate school, it is more likely that the student graduated with honors.

True

False

My son is special needs in high school and selute mute in school. Now, that we are doing google meet, and classroom meet I notice my son will take through the computer. I want to share with the school as this Covid 19 is not a good thing, my son is benefiting from it.? He is really engaged in his schoolwork at home as well?
