We are testing an effect of a potion that claimed to improve injured people's injuries with 80% of chance. The potion is given to 20 injured people and we observed the number "P" of people who improved. The hypothesis is 0.8 vs. H,: p < 0.8 Use the rejection region RR = {y<12}

The following is a list of 14 measurements. -1, -38, -59, -12, −5, −77, −42, −50, −68, −62, −82, −9, −80, 42 Send data to calculator Suppose that these 14 measurements are respectively labeled x₁, x2, X₁4. (Thus, −1 is labeled x₁, -38 is labeled .x₂, and so on.) Compute the following. 14 Σ (*; -48) i=1 0 X

Taylor Swift is interested in learning what proportion of her fans want her to re-record her masters, so she takes a simple random sample of 500 fans and asks them.  Of the 500 fans, 487 of them (97.4%) respond that they want her to re-record all of her masters.  What is the parameter and what is its value?   a. The parameter is the average number of all Taylor Swift fans who want her to re-record her masters, which is unknown.   b. The parameter is the proportion of the sampled Taylor Swift fans who want her to re-record her masters, which is unknown.   c. The parameter is the group of the sampled Taylor Swift fans who want her to re-record her masters, which is 487.   d. The parameter is the proportion of the sampled Taylor Swift fans who want her to re-record her masters, which is 0.974.   e. The parameter is the proportion of all Taylor Swift fans who want her to re-record her masters, which is unknown.   f. The parameter is the proportion of all…
