A random sample of 12 song lengths (in minutes) on a playlist found: = 278.3, s = 19. Build a 80% CI for the population mean length of a song on the playlist. Round all intermediate calculations to two decimals, then construct the Cl and enter like this: (min,max). Note: if you use a built-in Cl command on a calculator/computer, you might get marked wrong due to rounding. Use the formulas given in the text/notes. a. Since n < 30, We use a Z-interval O We use s, not o O It is important that song lengths be normally distributed O We use a T-interval b. The Cl is: Submit Question

The highway department wants to estimate the proportion of vehicles on a Toll road at KM 25 between midnight and 5:00 A.M. The department head wanted to see how many 18-wheel tractor trailers passed along the road. These estimates will be used to determine road improvement and construction considerations and in road patrol planning. The department head asked researchers to calculate the estimated vehicles at different locations on the inter-island road over the past 7 days. Of the 3,481 vehicles counted, 927 were 18 wheelers. However, out of a total of 927, there were 74 who had accidents, so the sample was calculated based on the results of reducing the number of accidents. Determine the point estimate for the proportion of vehicles traveling on KM 25 during this time period which are 18 wheelers! (Assume the confidence level is 99%). What is the benefit of estimating the estimated value in this case (analyze the answers you have obtained)?
Assume that the readings on the thermometers are normally distributed with a mean of 0° and standard deviation of 1.00°C. Assume 3.4% of the thermometers are rejected because they have readings that are too high and another 3.4% are rejected because they have readings that are too low. Draw a sketch and find the two readings that are cutoff values separating the rejected thermometers from the others. Click to view page 1 of the table. Click to view page 2 of the table. Which graph represents the region in which thermometers are rejected? Choose the correct graph below. O A. O C. O B. C Q 18 1 The cutoff values are degrees.

Radon is a gas emitted from the ground that can collect in houses in buildings. At certain levels it can cause lung cancer. Radon concentrations are measured in picocuries per liter (pCi/L). A radon level of 4 pCi/L is considered “acceptable” Radon levels in a house vary from week to week. In one house, a sample of 6 weeks had the following readings for radon level (in pCi/L): 1.9 2.8 3.9 3.9 4.2 5.7 Find the variance and standard deviation (definitional formula). Show your work using a table.
