6. At Pierre’s Coffee Shop, 65% of customers order coffee, 20% order tea, and 11% order fruit juice, while 4% do not order anything to drink. In addition, 39% order a muffin, 26% order a bagel, and 23% order a Danish, while 12% do not order anything to eat. Finally, 8% of customers order both tea and a Danish, and 47% of people order fruit juice given that they have ordered a muffin. Assume that an individual customer will not...

A rare form of malignant tumor occurs in 11 children in a million, so its probability is 0.000011. Four cases of this tumor occurred in a certain town, which had 16,616 children. a. Assuming that this tumor occurs as usual, find the mean number of cases in groups of 16,616 children. b. Using the unrounded mean from part (a), find the probability that the number of tumor cases in a group of 16,616 children is 0 or 1. c. What...
Research studies suggest that the likelihood a drug offender will be convicted of a drug offense within two years after treatment for drug abuse may depend on the person's educational level. The proportions of the total number of cases that fall into four education/conviction categories are shown in the table below: Education Convicted Not convicted Total 10 or more years of education 0.10 0.30 0.40 Less than 10 years of education 0.25 0.35 0.60 Total 0.35 0.65 1.00 Suppose a...
The Food Marketing Institute shows that 15% of households spend more than $100 per week on groceries.

Use z-table.Calculate ( ), the standard error of the proportion of households spending more than $100 per week on groceries (to 4 decimals).What is the probability that the sample proportion will be within +/- 0.02 of the population proportion (to 4 decimals)?What is...
The Food Marketing Institute shows that 16% of households spend more than $100 per week on groceries. Assume the population proportion is p = 0.16 and a sample of 900 households will be selected from the population. Use z-table. Calculate (), the standard error of the proportion of households spending more than $100 per week on groceries (to 4 decimals).
