An observational study is described. Identify the specified element.At St. Luke's hospital in 1998, 674 women were diagnosed with breast cancer. Five years later, 88% of the Caucasian women and 83% of the African American women were still alive. Determine the nature and scope of the conclusion the study can reach. Choose the best answer below: A. Since there is no random assignment, there is no way to know that being Caucasian causes women with breast cancer an increased chance of surviving five years; there may have been confounding variables. B. For women with breast cancer, being Caucasian causes an increased chance of surviving five years. C. Since there is no random assignment, there is no way to know that being Caucasian causes women with breast cancer an increased chance of surviving five years; there may have been lurking variables. D. For Caucasian and African American women with breast cancer, attending St. Luke's hospital causes an increased chance of surviving five…
Let the sample space be S={1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. Suppose the outcomes are equally likely. Compute the probability of the event E={2, 3, 6}. Question content area bottom Part 1 P(E)=enter your response here (Type an integer or a decimal. Do not round.)
A survey asks 1100 workers, "Has the economy forced you to reduce the amount of vacation you plan to take this year?" Forty-six percent of those surveyed say they are reducing the amount of vacation. Ten workers participating in the survey are randomly selected. The random variable represents the number of workers who are reducing the amount of vacation. Decide whether the experiment is a binomial experiment. If it is, identify a success, specify the values of n, p, and q, and list the possible values of the random variable x. Is the experiment a binomial experiment? No Yes What is a success in this experiment? Selecting a worker who is not reducing the amount of vacation Selecting a worker who is reducing the amount of vacation This is not a binomial experiment. Specify the value of n. Select the correct choice below and fill in any answer boxes in your choice. O A. n= B. This is not a binomial experiment. Specify the value of p.

When two births are randomly selected, the sample space for genders is bb, bg. gb, and gg. Assume that those four outcomes are equally likely. Construct a table that describes the sampling distribution of the sample proportion of girls from two births. Does the mean of the sample proportions equal the proportion of girls in two births? Does the result suggest that a sample proportion an unbiased estimator of a population proportion? For the entire population, assume the probability of having a boy is the probability of having a girl is , and this is not affected by how many boys or girls have previously been born. 2 Determine the probabilities of each sample proportion.

You want to see if a card dealer is favoring one suit over another. You observe the dealer pick a card, put it back in the deck, shuffle, and then repeat the process 224 times. The results are displayed in the table below. Use an αα = 0.05 significance level. Complete the rest of the table by filling in the expected frequencies:Frequencies of Suits Dealt Outcome Frequency Expected Frequency Spades 60 Hearts 63 Diamonds 59 Clubs 42 What are the null and alternative hypotheses?H0:H0: Ha:Ha: The degrees of freedom = The test-statistic for this data = (Please round your answer to 3 decimal places.) Based on this, we should reject the null fail to reject the null accept the null The final conclusion is ... At a sigificance level of 5%, there is insufficient evidence to conclude that the distribution of suits is not uniform. At a sigificance level of 5%, there is sufficient evidence to conclude that suits and cards are dependent. At a…
