Question:

Example 4, on whether dogs can detect bladder cancer by selecting the correct urine specimen (out of seven), used the normal sampling to find the P-value. The normal approximates a P-value using the binomial That binomial P-value is more appropriate when either expected count is less than 15. In Example 4, n was 54, and 22 of the 54 selections were correct.
a. If H0: p = 1/7 is true, X = number of correct selections has the binomial with n = 54 and p = 1/7. Why?
b. For Ha: p 7 1/7, with x = 22, the P-value using the binomial is P(22) + P(23) + g + P(54), where P (x) denotes the binomial probability of outcome x with p = 1/7. (This equals 0.0000019.) Why would the P-value be this sum rather than just P(22)?
Distribution
The word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
