A survey is carried out by the finance department to deter-mine the distribution of household size in a certain city. They draw a simplerandom sample of 1,000 households. Afper several visits, the interviewers findpeople at home in only 653 of the sampfe households. Rather than face such ahigh non-response rate, the department draws a second batch ofhouseholds, and uses the first 347 completed interviews in the second batch to bring thesample up to its planned strength of 1,000 households. The department counts3,087 people in these 1,000 households, and estimates the average householdsize in the city to be about 3.1 persons.

Is this estimate likely to be too low, too high, or about right?

Given this information, which expression must represent the value of b?

The table shows population statistics for the ages of best actor and best supporting actor winners at an awards ceremony. the distributions of the ages are approximately bell-shaped. compare the z-scores for the actors in the following situation. best actor best supporting actor muequals42.0 muequals49.0 sigmaequals7.3 sigmaequals15 in a particular year, the best actor was 59 years old and the best supporting actor was 45 years old. determine the z-scores for each. best actor: z equals best supporting actor: z equals (round to two decimal places as needed.) interpret the z-scores. the best actor was (more than 2 standard deviations above more than 1 standard deviation above less than 1 standard deviation above less than 2 standard deviations below) the mean, which (is not, is) unusual. the best supporting actor was (less than 1 standard deviation below more than 1 standard deviation above more than 2 standard deviations below more than 1 standard deviation below) the mean, which (is is not) unusual.
