According to a Gallup poll, fifty-one percent of US adults oppose hydraulic fracturing (fracking) as a means of increasing the production of natural gas and oil in the USA. You randomly select eight US adults. Find the probability that the number that oppose fracking for this purpose is

Exactly two

Less than five

At least three

Solutions

Expert Solution

It is a case of Binomial distribution because the probability of an event is fixed , there are fixed number of trails and there are two events only,

the two events are opposing hydraulic fracturing and not opposing hydraulic fracturing

sixty four percent of U.S. adults oppose hydraulic fracturing (fracking) as a means of increasing the production of natural gas and oil in the United States. You randomly select six U.S. adults. Find the probability that the number of U.S. adults who oppose fracking as a means of increasing the production of natural gas and oil in the United States is (a) exactly three, (b) less than four, and (c) at least three.

A large portion of US oil production comes from hydraulic fracturing (fracking). Production from fracked wells quickly declines, requiring constant drilling of new wells and installation of associated pipelines to keep production at current high levels. Assume that the Trump Administration carries out the threat to levy steep tariffs on imported steel. Companies that supply pipe to the oil industry for wells and pipelines see steep price increases for steel and have to raise their prices. Fill in the table...

Hydraulic fracturing (fracking) is a technique that extracts oil and natural gas from underground by injecting pressurized liquids to create fractures in bedrock formations. In recent (pre-COVID) years, the fracking industry has experienced a boom in the United States and worldwide (in China, Australia, UK). Supporters argue that fracking leads to economy-wide benefits by increasing the supply of natural gas and thus lowering gas prices (by almost 50% from 2000 to 2010). This has led to economy-wide benefits for energy...

Physical Sciences. Hydraulic fracturing, or fracking, is a method used to extract natural gas from deep shale deposits. This process involves over 500 chemicals and millions of gallons of water. In a random sample of fracking wells, the mean depth was 8000 feet. Assume the standard deviation is 440 feet and the distribution of depths is approximately normal. (a) What proportion (±±0.01) of wells have depths between 7120 and 8880 feet? (b) What proportion (±±0.0001) of wells have depths less...

According to a Gallup poll, 11.55% of American adults have diabetes. A researcher wonders if the rate in her area is higher than the national rate. She surveys 150 adults in her area and finds that 21 of them have diabetes. 1) If the region had the same rate of diabetes as the rest of the country, how many would we expect to have diabetes? 2) Suppose you are testing the hypothesis that the diabetes rate in this area differs...

In 2007, a Gallup poll estimated that 45% of U.S. adults rated their financial situation as “good.” We want to know if the proportion is smaller this year. We gather a random sample of 100 U.S. adults this year and find that 39 rate their financial situation as “good.” Use the output from StatCrunch to complete the following statements about the p-value. Use numbers from the output to fill in the blanks. The p-value is the probability of observing a...
