Please help! :< STATISTICS AND PROBABILITY (PLEASE SHOW your COMPLETE & CLEAR solutions) RATE WILL BE GIVEN The owner of a fast-food shop claims more than 45% of the household within 5-kilometer radius of the fast-food shop have at least one member who eats at the fast-food shop at least once a week. In a sample of 150 households in the area, an investigator found that members of 60 households did so. Do these data provide sufficient evidence to support the fast-food shop owner’s claim? Use 95% level of confidence. Answer the following: a. State the null and alternative hypothesis (in words and in symbols) and identify the claim. b. Find the critical value/s. c. Compute the test value. d. Make the decision (include a normal curve to show where the test value falls). e. Summarize the results.

Supposed a firm conducted a survey of workers involving the variable ‘’skill’’ and ‘educational level’. The survey revealed that 50% of the workers are elementary school graduate (E), 40% are secondary school Graduates (S) and 10% are college and above Graduates (C). If on the basis of skill, the survey revealed that 10% of Elementary school Graduate are unskilled, 5% of secondary school Graduate are unskilled, and 2% of college and above Graduates are unskilled. Suppose a worker is selected randomly and is found to be unskilled. What is the probability that the worker is a College Graduate?
A study was conducted to determine whether automobile repair charges are higher for female customers than for male customers. Twenty auto repair shops were randomly selected from the telephone book. Two cars of the same age, brand, and engine problem were used in the study. For each repair shop, the two cars were randomly assigned to a man and woman participant and then taken to the shop for an estimate of repair cost. The repair costs (in dollars) are given in the table.

In a famous study done in the 1960s two dolphins, Doris and Buzz, were trained to work together to earn fish. Doris was shown a light underwater. If the light was on steadily, her partner Buzz on the other side of the tank needed to press a button on the right for them to earn fish. If the light was blinking, he needed to press a button on the left. At one point in the study, the researcher hung a canvas in the middle of the tank in such a way that Buzz could not see the light. After looking at the light, Doris "swam near the curtain and began to whistle loudly. Shortly after that Buzz whistled back and then pressed the [correct] button". (Tintle, Rossman and Chance, MAA Prep Workshop) Of course, getting it right once was not enough to convince the scientists that there was really communication going on. It turned out, that in 15 out of 16 trials the dolphin pushed the correct button. Of course, it is possible that this happened just out of random chance - that the second dolphin just…

"Domestic cats kill many more wild birds in the United States than scientists thought," states a recent article. Researchers used a sample of n = 140 households in the US with cats to estimate that 35 % of household cats in the US hunt outdoors. 'Milius, S., "Cats kill more than one billion birds each year," Science News, 183(4), February 23, 2013, revised March 8, 2014. Data approximated from information give in the article. (a) Find a 95 % confidence interval for the proportion of household cats in the US that hunt outdoors. Round your answers to three decimal places. The 95 % confidence interval is to
