The power of a test is the probability that the test will find convincing evidence for Ha when a specific alternative value of the parameter is true.
Stated another way, power is equivalent to
rejecting H0 when you should reject H0.
failing to reject H0 when you should reject H0.
rejecting H0 when you should not reject H0.

The probability of obtaining two heads and two tails
(Type an integer or a fraction.)
The data represent the results for a test for a certain disease. Assume one individual from the group is randomly selected. Find the probability of getting someone who tested positive, given that he or
she did not have the disease.
The probability is approximately. (Round to three decimal places as needed.)

- Explains it correctly not copy paste.arrow_forwardHallux abducto valgus (call it HAV) is a deformation of the big toe that often requires surgery. Doctors used X-rays to measure the angle (in degrees) of deformity in 38 consecutive patients under the age of 21 who came to a medical center for surgery to correct HAV. The angle is a measure of the seriousness of the deformity. Here are the data. 282014 311930 271429 351919 362451 271525 273128 172726 302130 282239 292030 131920 1825 It is reasonable to regard these patients as a random sample of young patients who require HAV surgery. Carry out the Solve and Conclude steps of a 95% confidence interval for the mean HAV angle in the population of all such patients.
