According to the pew research center, the proportion of the american population who use only a cellular telephone (no landline) is 37%. jason claims that the proportion of young american adults who do not have a landline is greater than 37%. he conducts a survey with a sample of randomly selected young american adults and finds that 38% do not have landlines. if we set up our null and alternative hypotheses as follows: h 0 : p = 0.37 h a : p > 0.37 and find that: "p-value"=0.418. does this provide enough evidence to support jason’s claim? use an α=0.05 level of significance.
a. since the p-value < α, do not reject the null hypothesis.
b. since the p-value > α, do not reject the null hypothesis.
c. since the p-value < α, reject the null hypothesis.
d. since the p-value > α, reject the null hypothesis.
