According to a newspaper, 59% of high school seniors have a driver's license proportion who have a driver's license.
a. What value should we expect for our sample proportion?____%
b. What is the standard error?______
c. Use your answers to parts (a) and (b) to complete this sentence:
We expect _____% to have their driver's license, give or take_______%

d. Suppose we increased the sample size from 100 to 300. What effect would this have on the standard error? Recalculate the standard error to see if your prediction was correct.

We should expect a sample proportion of 59%. The other answers are given below.

A population percentage, abbreviated p, is the proportion of people in a population that share a specific attribute. The sample percentage, abbreviated p, is the proportion of people in a sample who share a specific attribute.

Thus,

a) We We should expect a sample proportion of 59%.

b) SE = √P x (1-p ) / n) = √ (0.59 x (1-0.59)/100 = 0.0491833305 or 0.049

c) we shold expect 50% ot have their drivers license or take 4.9%

d) Increasing the sample from 100 to 300 will reduce the standard error. This new standard error will be:

Standard Error =   √(0.59 x (1- 0.59) /300) = 0.028

The blue catfish (Ictalurus Furcatus) is the largest species of North American catfish. The current world record stands at 143 pounds, which was caught in the John H. Kerr Reservoir (Bugg's Island Lake) located in Virginia. According to American Expedition, the average weight of a blue catfish is between 20 to 40 pounds. Given that the largest blue catfish ever caught was at the John H. Kerr Reservoir, you believe that the mean weight of the fish in this reservoir is greater than 40 pounds. Use the data below, which represents the summary statistics for 53 blue catfish caught at this reservoir, and a 0.05 significance level to test the claim that the mean weight of the fish in the John H. Kerr Reservoir is greater than 40 pounds.

(1) The automated technology boom has been exciting to watch, but there are growing concerns about its impact on employment. (2) In fact, reports about automation pointing to a possible employment crisis for younger generations are becoming rather common. (3) A 2018 article in the Los Angeles Times reported that 63 percent of tasks performed by workers in three California cities—Riverside, San Bernardino, and Ontario—could be automated in the future. (4) Rapid technological advances are already affecting workers, with the following jobs being replaced by robots at the fastest rates: etcher/engraver, crop farmworker, insurance claims examiner, travel agent, robotics engineer, and customs broker.

(5) How can we prepare for this brave new world we’ll soon inhabit? (6) The two approaches that stand to have the greatest impact are education reform and basic income (BI) programs. (7) In terms of education, we need to ensure that schools offer training in skills that reflect the evolving labor landscape. (8) Chaffey College, for instance, in Rancho Cucamonga, California, has started offering cutting-edge courses in construction and logistics, two of the fastest growing industries in the region. (9) Chaffey is thus a model of education reform, expanding and revising its course offerings in response to local labor demands.

(10) BI is the more controversial of the two proposed reforms. (11) But it’s already being tried on a small scale in Stockton, California, where selected residents are receiving $500 per month. (12) Some business and labor union leaders are dismissive of this new social safety net, suggesting that it discourages people from working, but tech industry leaders argue persuasively that BI can provide workers with needed resources and flexibility to take jobs in the freelance or “gig” economy. (13) Employment issues have already inspired BI pilot programs in Finland, Kenya, Canada, and the Netherlands, showing that there is emerging international support for this strategy. (14) Hopefully, as automation disrupts more industries, public acceptance of BI will increase in the United States as well.

(15) We can’t just sit around twiddling our thumbs as new tech keeps changing the game in a bunch of businesses.
