A spokesperson for the National Association of Broadcasters (NAB) claims that 80% of all satellite radio subscribers have a satellite radio receiver in their car. A random sample of 501 satellite radio subscribers are surveyed and 396 of them had a satellite receiver in their car. Consider a test of the NAB spokesperson's claim. (a) Set up the null and alternative hypotheses if you believe that the spokesperson's claim is too high. Be sure to define the parameter used in your hypotheses. (b) What is the test statistic

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent

first one because it can't have a fraction in it

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
