Consider a multinomial experiment with n = 260 and k = 4. The null hypothesis to be tested is H0: p1 = p2 = p3 = p4 = 0.25. The observed frequencies resulting from the experiment are (Use Table 3):
Category1 2 3 4 Frequency85 58 89 75
a. Choose the appropriate alternative hypothesis. All population proportions differ from 0.25.Not all population proportions are equal to 0.25.
b. Calculate the critical value at the 10% significance level. (Round your answer to 3 decimal places.)
Critical value
c. Calculate the value of the test statistic. (Round intermediate calculations to 4 decimal places and your final answer to 2 decimal places.)
Test statistic
d. What is the conclusion to the hypothesis test? Do not reject H0 since the value of the test statistic exceeds the critical value.Reject H0 since the value of the test statistic does not exceed the critical value.Do not reject H0 since the value of the test statistic does not exceed the critical value.Reject H0 since the value of the test statistic exceeds the critical value.
What is the independent variable of this experiment? How many levels does it have? What is the dependent variable? On what scale (nominal, ordinal, interval, ratio) was it measured
a regression of height x in inches on hourly earnings y in dollars yields the following resultsn26 ssr200 sst1000 r.447
(a) Prove that any intersection of topologies on a set is a topology. (b) Prove that for any collection U of subsets of a set X , there is a smallest topology on X including U , using part (a) (rather than subbases).
Use the .05 level. (a) Use the steps of hypothesis testing, (b) figure the effect size for the study; and (c) explain your answers to (a) and (b) to someone who has never had a course in statistics.
