The amount of time adults spend watching television is closely monitored by firms because this helps to determine advertising pricing for commercials Complete parts a through d a Do you think the variable weekly time spent watching television would be normally distributed If not what shape would you expect the variable to have A The variable weekly time spent watching television is likely uniform not normally distributed B The variable weekly time spent watching television is likely symmetric but not normally distributed OC The variable weekly time spent watching television is likely normally distributed D The variable weekly time spent watching television is likely skewed right not normally distributed E The variable weekly time spent watching television is likely skewed left not normally distributed b According to a certain survey adults spend 2 45 hours per day watching television on a weekday Assume that the standard deviation for time spent watching television on a weekday is 1 93 hours If a random sample of 40 adults is obtained describe the sampling distribution of x the mean amount of time spent watching television on a weekday x is approximately normal with Hx 2 45 and ox 0 305160 Round to six decimal places as needed c Determine the probability that a random sample of 40 adults results in a mean time watching television on a weekday of between 2 and 3 hours The probability is 0 8941 Round to four decimal places as needed d One consequence of the popularity of the Internet is that it is thought to reduce television watching Suppose that a random sample of 35 individuals who consider themselves to be avid Internet users results in a mean time of 2 03 hours watching television on a weekday Determine the likelihood of obtaining a sample mean of 2 03 hours or less from a population whose mean is presumed to be 2 45 hours
