1)      It is estimated that 17.4% of all US households own a Roth IRA.  The American Association of University Professors (AAUP) believes this figure is different among their members and commissions a study.   
 
a)  If 150 out of a random sample of 750 AAUP members own Roth IRA’s, is this sufficient evidence to support the AAUP belief at the α=0.05 level? (You must run a hypothesis test)
 
 
 
 
b)  Based on your results from (a), if an error was made, would it be type I or type II error?  Explain the error you chose in the context of the question.

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

for future students the answer is b

-lavira: )

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
