Z-test
attendance quiz: test of hypothesis (50 points)
q1. a herd of 1500 cattle was fed a special high-protein grain for a month. a random sample of 50 cattle was weighed and had gained an
average of 7.4 pounds. if the standard deviation of weight gain for the entire herd is 5.3 pounds, test the hypothesis that the average weight
gain per cow for the month was more than 7 pounds.
(a) state the null and alternative hypothesis
(b) calculate the test statistic. (round your answer to two decimal places
(c) calculate the p-value. round your answer to four decimal places.)
(d) based on a = 0.05, what is the correct conclusion for the hypothesis test?

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
