The FleetFoot Shoe company claims that the average yearly salary of its workers is $29,800. The Union believes that the average is much less. A random sample of 57 employees shows their average salary to be $29,500 with a population standard deviation of $1200. Test the hypothesis using a 3% level of significance. Using the classical approach: (Step 4) Find the Z-value: -1.89 -1.90 -1.87 -1.88

The average monthly, entry-level salary for fresh graduates was reported as $2,800. A recruiting agency believed that the mean salary of fresh entry is lower than this. The recruiting office randomly surveyed 25 entry-level graduates and found that the sample means salary is $2,200, and the sample standard deviation is $1800. Assuming t- distribution is followed, answer the following questions. Use: H0 : u>2800 H1 : u

A recent report claims that Americans spend an average of $11 per day on lunch. You believe that people who live in Philadelphia, PA spend significantly less on lunch per day than that. In order to test this, you randomly sampled n=100 Philadelphia residents and asked them how much they spend on lunch everyday. The sample average of these respondents was $10.92 with a sample standard deviation of $1.07. If you want to test the null hypothesis that H0: mean=11 vs Ha: mean <11.what is the value of the test statistic?

A researcher conducted an Internet survey of 400 students at a particular college to estimate the average amount of money students spend on groceries per week. The data are normally distributed, with the highest weekly amount being $225 and the lowest weekly amount being $80. The sample mean is $150. What is the margin of error (ME), rounded to the nearest hundredth, for this college? Hint: where SD is the standard deviation, XH is the high value, and XL is the low value. Hint: where SD is the standard deviation and N is the sample size. a ME = ±$2.53 b ME = ±$966.67 c ME = ±$14.50 d ME = ±$2.42

A grocery store has an average sales of $6,000 per day. The store introduced several advertising campaigns in order to increase sales. To determine whether or not the advertising campaigns have been effective in increasing sales, a sample of 100 days of sales was selected. It was found that the average was $6,550 per day. From past information, it is known that the standard deviation of the population is $1,500. Find the value of the test statistic. 0.037 0.367 3.67 36.67
