Introduction to hypothesis tests for a population proportion usin..
The magazine Tech Worx reported that 91% of software engineers rate the company they work for as "a great place to work." As a veteran headhunter, you
claim the percentage given in the report is not correct. In a survey of 220 randomly chosen software engineers, 210 rated the company they work for as "a
great place to work."
Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to support your claim that the
proportion, p, of all software engineers who rate the company they work for as "a great place to work" is not 91%.
(a) State the null hypothesis H and the alternative hypothesis H, that you would use for the test.
Но: р — 0.91
p
O<O
OSO
H1: p + 0.91

(b) For your hypothesis test, you will use a Z-test. Find the values of np and n(1-p) to confirm that a Z-test can be used. (One standard is that np210 and
n(1-p) >10 under the assumption that the null hypothesis is true.) Here n is the sample size and p is the population proportion you are testing.

п (1-р) -О
(c) Perform a Z-test. Here is some information to help you with your Z-test.
• Zo os is the value that cuts off an area of 0.05 in the right tail of the distribution.

A farsighted eye is corrected by placing a converging lens in front of the eye. The lens will create a virtual image that is located at the near point (the closest an object can be and still be in focus) of the viewer when the object is held at a comfortable distance, usually taken to be 25.0 cm. If a person has a near point of 79.5 cm, what power reading glasses should be prescribed to treat this hyperopia? Assume that the distance from the eye to the lens is negligible. power: 0.0275 Incorrect. diopters

Consider the following problem: A farmer has 3600 ft of fencing and wants to fence off a rectangular field that borders a straight river. He does not need a fence along the river (see the figure). What are the dimensions of the field of largest area that he can fence? (Let x be the width of the field in feet and l be the length of the field in feet.) (a) Experiment with the problem by drawing several diagrams illustrating the situation. Calculate the area of each configuration, and use your results to estimate the dimensions of the largest possible field. (Round your answers to the nearest hundred feet.) (b) Find a function that models the area of the field in terms of one of its sides (c) Use your model to solve the problem, and compare with your answer to part (a)
Fifty-four wild bears were anesthetized, and then their weights and chest sizes were measured and listed in a data set. Correlation Results Results are shown in the accompanying display. Is there sufficient evidence to support the claim that there is a linear correlation between the weights of bears and their chest sizes? When measuring an anesthetized bear, is it easier to measure chest size than weight? If so, does it appear that a measured chest size can be used to predict the weight?
