United States has about 2 million of farm. Data from USDA indicates that 60% of farms earn a gross cash farm income less than $10,000 per year. The population proportion with annual gross cash farm income less than $10,000 is p = .6 and a sample of 800 farms will be selected from the population. a. Show the sampling distribution of 𝒑̅, the sample proportion of farms earning a gross cash farm income less than $10,000 per year. b. What is the probability that the sample proportion will be within ± .0262 of the population proportion? c. Answer part (b) for a sample of 1,600 households. Questions on Sampling 4. A random sample of 100 credit sales in a department store showed an average sale of $120.00. From past data, it is known that the standard deviation of the population is $40. a. Determine the standard error of the mean. b. With a .95 probability, determine the margin of error. c. What is the 95% confidence interval of the population mean?

. Consider an object of mass m = 1, hanging on a spring with spring constant k = 25. Let y(t) be the displacement of the object from resting position (y is positive downward). (a) Assuming there is no friction, describe the motion of the object. That is, discuss whether, for example, y(t) increases in time, decreases in time, or whether it oscillates. If it oscillates, does the amplitude increase, decrease, or stay the same

A positive point charge exerts force on a wire that is straight, long, and uniformly positively charged. By what number would the charge per unit length of the wire have to be multiplied to cause the force magnitude to be increased three-fold if also the charge of the point charge is increased by a factor of 100? Assume all other parameters remain unchanged. Group of answer choices A number <0.038 A number ≥0.038 and <0.073 A number ≥0.073 and <0.15 A number ≥0.15 and <0.31 A number
