- 3. A genetics experiment involves a population of fruit flies consisting of 2 males named Albert and Billy and 2 females named Carla and Dana. Assume that two fruit flies are randomly selected with replacement. a. After listing the possible samples and finding the proportion of males in each sample, use a table to describe the sampling distribution of the proportion of males. Proportion of males Probability 0.5 1 (Type integers or fractions.) b. Find the mean of the sampling distribution. (Round to two decimal places as needed.) c. Is the mean of the sampling distribution [from part (b)] equal to the population proportion of males? If so, does the mean of the sampling distribution of proportions always equal the population proportion? OA. No, the sample mean is equal to the population proportion of males. These values are not always equal, because proportion is an unbiased estimator. OB. Yes, the sample mean is equal to the population proportion of males. These values are always equal,…A breakfast cereal includes marshmallow shapes in the following distribution: 10% stars, 10% crescent moons, 20% rockets, 40% astronauts, 20% planets. We are interested in examining the proportion of rockets in a random sample of 2000 marshmallows from the cereal. (a) Sketch the population distribution of marshmallow shapes. (b) Suppose you were to collect a random sample of 2000 marshmallow shapes. Sketch the distribution of sample data you would expect to see. How many rockets would you expect to see in your sample?Question 4- What is a sampling distribution? Provide an example.

- I have a probabilty and sample spaces geometry question.In the EAI sampling problem, the population mean is $71800 and the population standard deviation is $4000. For n=30, there is a .5064 probability of obtaining a sample mean within plus or minus 500 of the population mean.Create real life problem situations in psychological field that illustrates the use of each of the following probability and non- probability sampling techniques. 1.

- for a given level of the probability of rejecting the null hypothesis when its true, if we want to decrease the probability of not rejecting null hypothesis when it is false the sample must A) decrease B) remain the same C) increase D) increase or decrease since it has no impact on probability of not rejecting null hypothesis when it’s falseAre birthdays "evenly distributed" throughout the year, or are they more common during some parts of the year than others? Owners of a children's toy store chain in the Northwest asked just this question. Some data collected by the chain are summarized in the table below. The data were obtained from a random sample of 190 people. The birthdate of each person was recorded, and each of these dates was placed into one of four categories: winter (December 21-March 20), spring (March 21-June 20), summer (June 21-September 20), and fall (September 21-December 20). The numbers in the first row of the table are the frequencies observed in the sample for these season categories. The numbers in the second row are the expected frequencies under the assumption that birthdays are equally likely during each season of the year. The bottom row of numbers gives the following value for each of the season categories. Answer the following to summarize the test of the hypothesis that birthdays are equally….
