Examine the following two-factor analysis of variance table:Source SS df MS F-RatioFactor A 162.79 4 Factor B 28.12 AB Interaction 262.31 12 Error ________ ___ Total 1,298.
74 84 Does the ANOVA table indicate that the levels of factor B have equal means? Use a significance level of 0.05.A) Fail to reject H0. Conclude that there is not sufficient evidence to indicate that at least two levels of Factor B have different mean responses.
B) Reject H0. Conclude that there is sufficient evidence to indicate that at least two levels of Factor B have different mean responses.
C) Fail to reject H0. Conclude that there is sufficient evidence to indicate that at least two levels of Factor B have different mean responses.
D) Reject H0. Conclude that there is not sufficient evidence to indicate that at least two levels of Factor B have different mean responses.
Question 2
An issue that faces individuals investing for retirement is allocating assets among different investment choices. Suppose a study conducted 10 years ago showed that 65 of investors preferred stocks to real estate as an investment.
In a recent random sample of 900 investors, 540 preferred real estate to stocks. Is this new data sufficient to allow you to conclude that the proportion of investors preferring stocks to real estate has declined from 10 years ago? Conduct your analysis at the = 0.02 level of significance.A) Because z = -1.915 is not less than -2.055, do not reject H0. A higher proportion of investors prefer stocks today than 10 years ago.
B) Because z = -1.915 is not less than -2.055, do not reject H0. A lower proportion of investors prefer stocks today than 10 years ago.
C) Because z = -3.145 is less than -2.055, reject H0. A lower proportion of investors prefer stocks today than 10 years ago.
D) Because z = -3.145 is less than -2.055, reject H0. A higher proportion of investors prefer stocks today than 10 years ago.
