Example: Typical values reported for the mammogram which is used to detect breast cancer are sensitivity = .86, specificity = .88. Of the women who undergo mammograms at any given time, about 1% is estimated to actually have breast cancer. -Tree DiagramforMammogram? -ContingencyTable forMammogram? QUESTION 2: A) prevalance= .01 a) Find the probability of a positive test? b) Of the women who receive a positive mammogram, what proportion actually have breast cancer? c) if a woman tests negative, what is the probability that she does not have breast cancer?

Whatt is the long hand solution for You select a sample of n =36 participants and aask them to walk every day for at least 30 minutes. At the end of a month you give them the well-being scale and find M = 72. If you use a two-tailed test with alpha level equal to 0.05 to determine the impactof taking a daily walk on well-being, what is the probability that you have made a Type I error? How can you reduce the probability of making a Type I error?
How would you solve this?

Question 6 of 12 View Policies Current Attempt in Progress The following is a set of hypotheses, some information from one or more samples, and a standard error from a randomization distribution. > Test Ho H₁ H₂ VS H₂ H₁ H₂ when the samples have n₁ = n₂ = 60, x₁ = 35.4,₂ = 32.7, s₁= 1.23, and s₂ = 1.13. The standard error of ₁-₂ from the randomization distribution is 0.22. Find the value of the standardized z-test statistic. Round your answer to two decimal places.

A gambler complained about the dice. They seemed to be loaded! The dice were taken off the table and tested one at a time. One die was rolled 300 times and the following frequencies were recorded. Outcome 1 2 3 4 5 6 Observed frequency O 63 45 60 33 49 50 Do these data indicate that the die is unbalanced? Use a 1% level of significance. Hint: If the die is balanced, all outcomes should have the same expected frequency. (a) What is the level of significance? (b) Find the value of the chi-square statistic for the sample. (Round the expected frequencies to at least three decimal places. Round the test statistic to three decimal places.) What are the degrees of freedom?
hello I need answers to 3a,3b,3c please and thank you!
(a) State the null and alternative hypotheses.Ho= Ha= (b) Give the notation for the sample statistic.statistic symbol-statistic symbol (c) Give the value for the sample statistic. Value=# Use the randomization distribution to estimate the p-value? p-value=#
just the p value thank you
