Question

Conduct the hypothesis test and provide the test statistic, critical value and P-value, and state the conclusion. person selected 100 checks and recorded the cents portions of those checks. The table below lists randomly those cents portions categorized according to the indicated values. Use a 0.10 significance level to test the that the four categories are likely. The person expected that many checks for whole dollar amounts would result in a disproportionately high frequency for the first category, but do the results support that expectation? cents portion of check 0-24 25-49 50-74 75-99 Number 35 19 21 25 The test statistic is Type an integer or a decimal.) The critical value is (Round to three decimal places as needed.) The P-value is (Round to four decimal places as needed.) State the conclusion. Ho. There T to warrant rejection of the claim that the four categories sufficient evidence are equally likely. The results to support the expectation that the frequency for the first category is disproportionately high.

Explanation / Answer

From following results

Test statistic =6.08

Critical value=6.251

p-value=0.1078

Do not reject H0. There is not sufficient evidence to warrant rejection of the claim that the four categories are equally likely. The results do not appear to support the expectation that the frequency for the first category is disproportionately high.

Cents Number Oi Ei=100/4 (Oi-EI)^2/Ei 0-24 35 25 4 25-49 19 25 1.44 50-74 21 25 0.64 75-99 25 25 0 Total 100 100 6.08 Chi-Square 3 Degree of freedom=4-1 6.251 Critical Value=CHIINV(0.1,3) 0.1078 p-value=chidist(6.08,3)
