In a study of cell phone usage and brain hemispheric dominance, an internet survey was e-mailed to 6965 subjects randomly selected from an online group involved with ears. there were 1330 surveys returned. use a 0.01 significance level to test the claim that the return rate is less than 20%. use the p-value method and use the normal distribution as an approximation to the binomial distribution. identify the null hypothesis and alternative hypothesis. a. upper h 0: pequals0.2 upper h 1: pless than0.2 b. upper h 0: pgreater than0.2 upper h 1: pequals0.2 c. upper h 0: pequals0.2 upper h 1: pnot equals0.2 d. upper h 0: pnot equals0.2 upper h 1: pequals0.2 e. upper h 0: pless than0.2 upper h 1: pequals0.2 f. upper h 0: pequals0.2 upper h 1: pgreater than0.2 the test statistic is zequals nothing. (round to two decimal places as needed.) the p-value is nothing. (round to three decimal places as needed.) because the p-value is

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. 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.
