Question 2

2pts

Using only patients 1,2, and 3 in D from Question 6.8 from page 73 Rosner Study Guide (Chapter 06), we sample two paitnets with replacement and create a sampling distribution (just like slide 9 in lecture 5; call this new sample D2). Selectall correct statements::

Group of answer choices

Central Limit Theorem tells us that the sampling distribution will be binomial distribution

Mean of D2 is 132/9

Sandard deviation of D2 is 20.869

Sampling distribution of D2 can be estimated as N(132/9, 435.5)

Sampling distribution of D2 can be estimated as N(44/3, 1161.33)

Question 3

Selectall correct statementsrelated to Question 6.9 from page 73 Rosner Study Guide (Chapter 06):

Group of answer choices

Standard error of D will be closer to standard deviation of D than standard deviation of a sampling distribution from D.

Standard error of D will be closer to standard deviation of a sampling distribution from D than standard deviation of D.

Standard error and standard deviation can be the same for a different set of 10 patients.

Standard error of D can be used in sampling distribution from D as a variance of a binomial distribution

The sampling distribution from D can be estimated as a normal distributionwith the standard error of D as astandard deviation of the normal distribution

Question 4

Selectall correct statementsrelated to Question 6.10 from page 73 Rosner Study Guide (Chapter 06):

Group of answer choices

Larger the confidence, wider the interval

Interval of(,+)

(,+)has confidence of 0%

If we calculate the 90% confidence interval, it will be wider than (0.9, 29.3)

We can infer that if we do this hypertension study 100 times with different patients, there will be at most 5 studies that mean of difference will lie outside of (0.9, 29.3)

We can infer that if we do this hypertension study 100 times with different patients, there will be at least 5 studies that mean of difference will lie outside of (0.9, 29.3)

We can infer that if we do this hypertension study 100 times with different patients, there will be at exactly 5 studies that mean of difference will lie outside of (0.9, 29.3)

Question 5

1pts

Use hypertension example for questions 6.8 through 6.11 from page 73 Rosner Study Guide (Chapter 06). Assume that D is normally distributeD. Construct a 99% CI for the mean (NOTE: this question is different than question 6.10)?
