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. 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...
