an investigator analyze a leading digits from 772 checks issued by seven suspect companies. The frequencies were found to be 236,133,99,69,53,56,43,38, and 45 and those they just correspond to the leading digits of 1,2,3,4,5,6,7,8 and 9. if the observed frequencies are substantially different from the frequencies expected with benfords lash below the checks amounts of your to result from fraud. Use a 0.10 significance to test for goodness of fit with benfords law. Does it appear that the checks are the results of fraud?
Leading Digit: 1,2,3,4,5,6,7,8,9
Actual Frequency: 236,133,99,69,53,56,43,38,45
Benfords Law: 30.1%,17.6%,12.5%,9.7%,7.9%,6.7%,5.8%,5.1%,4.6%
a.) determine the normal and alternative hypothesis: H0= and H1=
b.) Test statistic x2=
c.) P-value=
d.) ____ H0. There __ Sufficient evidence to weren't rejection of the queen of the leading digits are from the population distribution that conforms to Benford's law. It ___ that the chexks are the result of fraud
