4-29. Suppose that we are testing Ho: μ = μo versus Mo H₁: μμo. Calculate the P-value for the following observed # values of the test statistic: (a) zo = 2.45 Zo (d) zo = 1.95 (b) zo = -1.53 (e) Zo= -0.25 (c) zo = 2.15 Zo

H0:μ=52.9H0:μ=52.9H1:μ<52.9H1:μ<52.9Your sample consists of 49 subjects, with a mean of 52.7 and standard deviation of 2.44.Calculate the test statistic, rounded to 2 decimal places. t=t=

A random sample of 17 adult male wolves from the Canadian Northwest Territories gave an average weight x1 = 98.6 pounds with estimated sample standard deviation s1 = 5.6 pounds. Another sample of 26 adult male wolves from Alaska gave an average weight x2 = 88.2 pounds with estimated sample standard deviation s2 = 6.0 pounds.   (a) Categorize the problem below according to parameter being estimated, proportion p, mean μ, difference of means μ1 – μ2, or difference of proportions p1 – p2. Then solve the problem. μp    μ1 – μ2p1 – p2 (b) Let μ1 represent the population mean weight of adult male wolves from the Northwest Territories, and let μ2 represent the population mean weight of adult male wolves from Alaska. Find a 99% confidence interval for μ1 – μ2. (Use 1 decimal place.) lower limit   upper limit   (c) Examine the confidence interval and explain what it means in the context of this problem. Does the interval consist of numbers that are all positive? all negative? of…

what is the relative frequency of yields in sample A that were greater than 21.5 and less than or equal to 22.5 q/ha? i am getting the wrong one. its saying mine is incorrect.
