4- Variance and Standard deviation (how far the data values lie from the mean) The mean, mode, and median do a nice job in telling where the center of the data set is, but often we are interested in more. For example, a pharmaceutical engineer develops a new drug that regulates iron in the blood. Suppose she finds out that the average sugar content after taking the medication is the optimal level. This does not mean that the drug is...

2. Hypothesis tests about a population mean, population standard deviation known Aa Aa Lenders tighten or loosen their standards for issuing credit as economic conditions change. One of the criteria lenders use to evaluate the creditworthiness of a potential borrower is her credit risk score, usually a FICO score. FICO scores range from 300 to 850. A consumer with a high FICO score is perceived to be a low credit risk to the lender and is more likely to be...

What does the variance or standard deviation tell you about a population that the mean does not tell you? The mean, median, and mode are three different statistical approaches to describe the middle individual in a population. Explain which of these statistics of location should be used when viewing a histogram ?

6. Expected value and standard deviation of the sample proportion (finite population)A Aa A local cell phone store just recelved a shipment of 267 cell phone chargers. The manager wants to estimate the number of defective cell phone chargers in the shipment. Rather than checking every cell phone charger, the manager plans to take a simple random sample of size 80 in order to estimate the proportion of defective cel phone chargers in the shipment. If the sample proportion of...

2. Central Limit Theorem Aa Aa E Imagine that you are doing an exhaustive study on the children in all of the preschools in your school district. You are particularly interested in how much time children spend with siblings on weekends. You find that for this population of 2,431 children, the average number of minutes spent with siblings on weekends is u = 350.23, with a standard deviation of o = 187.59. You select a random sample of 25 children...
