(a) suppose that a random sample of 400 television ads in the united kingdom reveals that 142 of these ads use humor. find a point estimate of and a 95 percent confidence interval for the proportion of all u. k. television ads that use humor. (round your answers to 3 decimal places.) pˆ = the 95 percent confidence interval is [ , ]. (b) suppose a random sample of 500 television ads in the united states reveals that 122 of these ads use humor. find a point estimate of and a 95 percent confidence interval for the proportion of all u. s. television ads that use humor. (round your answers to 3 decimal places.) pˆ = the 95 percent confidence interval is [ , ]. (c) do the confidence intervals you computed in parts a and b suggest that a greater percentage of u. k. ads use humor? , the u. k. 95 percent confidence interval is the maximum value in the confidence interval for the u. s. referencesebook & resources

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.
