A company conducted a survey on the number of hours employees spend on a particular task per week. The data collected from a sample of 10 employees are as follows: 5, 6, 7, 8, 9, 10, 10, 11, 12, 13. Calculate the standard deviation of the hours spent on the task per week.
Battery packs in electric go-carts need to last a fairly long time. The run-times (time until recharging is needed) of the battery packs made by a particular company are Normally distributed with a mean of 2 hours and a standard deviation of 20 minutes. Battery packs that have a runtime in the highest 10% of the run-time distribution are highly sought after by go-cart drivers. How long does the battery pack have to last for it to fall in this highly sought-after class? (Enter the number of hours as a whole number and the number of minutes as a decimal rounded to 1 decimal place.)
The Weschler Intelligence Scale for Children (WISC) is an intelligence test designed for children between the ages of 6 and 16. The test is standardized so that the mean score for all children is 100 and the standard deviation is 15. Suppose that the administrators of a very large and competitive school district wish to estimate the mean WISC score for all students enrolled in their programs for gifted and talented children. They obtained a random sample of 40 students currently enrolled in at least one program for gifted and talented children. The test scores for this sample are as follows: 117,142,112,99,107,109,109,121,121,125,116,123,110,105,110,111,95,128,103,106, 155,98,100,123,107,137,115,127,102,106,121,113,109,128,103,105,130,134,112,102 Click to download the data in your preferred format.

The height of women ages 20-29 is normally distributed, with a mean of 64.9 inches. Assume σ=2.4 inches. Are you more likely to randomly select 1 woman with a height less than 66.8 inches or are you more likely to select a sample of 14 women with a mean height less than 66.8 inches? Explain.
Scores on the GRE (Graduate Record Examination) are normally distributed with a mean of 506 and a standard deviation of 81. Use the 68-95-99.7 Rule to find the percentage of people taking the test who score between 425 and 506. The percentage of people taking the test who score between 425 and 506 is 68 %.
Suppose the population has a normal distribution with a true mean of 100 and a standard deviationof 50. You are taking repeated samples of size 25. What is the expected mean of the samplingdistribution (? bar)?
pizza delivery chain advertises that it will deliver your pizza in 35 minutes from when the order is placed. Being a skeptic, you decide to test and see if the mean delivery time is actually more than 35 minutes. For the simple random sample of 7 customers who record the amount of time it takes for each of their pizzas to be delivered, the mean is 39.4 minutes with a standard deviation of 5.5 minutes. Assume that the population distribution is approximately normal. Perform a hypothesis test using a 0.025 level of significance. Step 3 of 3 : Draw a conclusion and interpret the decision.
A random sample of size 40 is taken from a large population with mean 100 and standard deviation 16. What is the mean of the sampling distribution of the sample means?
The mean age when smokers first start is 13 years old with a population standard deviation of 1.8 years. A researcher thinks that smoking age has significantly changed since the invention of ENDS-electronic nicotine delivery systems. A survey of smokers of this generation was done to see if the mean age has changed. The sample of 33 smokers found that their mean starting age was 12 years old. What type of test should you use? A) z-test for population mean B) t-test for population mean C) z-test for population proportion
