The mean number of sick days an employee takes per year is believed to be about ten. Members of a personnel department do not believe this figure. They randomly survey eight employees. The number of sick days they took for the past year are as follows: 12; 4; 15; 3; 11; 8; 6; 8. Let x = the number of sick days they took for the past year. Construct a 95% confidence interval for the true mean or proportion. Round to the nearest hundredth (2 decimal places).
Match the scenarios with the appropriate measure of central tendency that should be used to compute them on the right. (Either mean or mode.) 1. Trying to understand the performance of students from their letter grades in the course. What measures of central tendency are appropriate for the situation? 2. A retailer sells diferent types of chocolate. Which measure of central tendency should the storeowner use to describe the most popular choclate? 3. You are trying to gauge how much you might need to spend to buy a house in a new locality. The data for the prices of the houses sold last year is available. The data shows some really expensive houses were sold in the locality and the price of no two houses seem to match in the sales data. What measures of central tendency are appropriate for the situation?

The Bureau of Alcohol, Tobacco, and Firearms (BATF) has been concerned about lead levelsin California wines. In a previous testing of wine specimens, lead levels ranging from 50 to 700parts per billion were recorded. How many wine specimens (at the least) should be tested if theBATF wishes to estimate the mean lead level for California wines to within 10 parts per billionwith 95% confidence?

21. Listening to music has long been thought to enhance intelligence, especially during infancy and childhood. To test whether this is true, a researcher records the number of hours that eight high-performing students listened to music per day for 1 week. The data are listed in the table. Music listening per day (in hours) 4.2 4.8 5.0 3.8 4.2 5.5 4.1 4.4 1. Find the confidence limits at a 95% CI for this sample. 2. Suppose the null hypothesis states that students listen to 3.5 hours of music per day. What would the decision be for a two-tailed hypothesis test at a 0.05 level of significance?
Report an appropriate hypothesis test for a positive linear relationship and use a 5% significance level. Explain the potential error in words, in context. In the answer options below I have used the phrase “a certain relationship” because I don’t want to give away exactly what type of relationship it is. Group of answer choices We would be accepting that there was a certain relationship between Sale amount and Tip when actually there wasn’t. We would not be accepting that there was a certain relationship between Sale amount and Tip when indeed there wasn’t. We would not be accepting that there was a certain relationship between Sale amount and Tip when actually there was. We would be accepting that there was a certain relationship between Sale amount and Tip when indeed there was.
