The communications regulator of a certain country released a report refuting an earlier report released by the same regulator. the new report indicates that cable subscribers would save as much as 9% on their cable television bills. the average monthly cable prices in the country were estimated to be $44.29. typically, such reports announce a margin of error of. say. $1.65 and a confidence level of 95%. suppose the standard deviation of the monthly cost of cable television bills was $8.00. complete parts a through c below. determine the sample size of the new study released by the regulator. the sample size is. (round up to the nearest whole number as needed.) calculate the sample size required to decrease the margin of error by a dollar. the sample size required is. (round up to the nearest whole number as needed.) a typical sample size used in national surveys in the country is 1.750 to 2.150. determine a range for the margin of error corresponding to this range of sample sizes. the range for the margin of error is from $ to $. (round up to the nearest cent. use ascending order.)
