Question 9 Question 9 9) Four different leadership styles used by Big-Six accountants 9) were investigated. As part of a designed groups (a total of 60 subordinates performed substandard field work on a 10-point scale-called the "substandard work scale". The objective is to compare the mean substandard work scales of the four leadership styles. The data on substandard work scales for all 60 observations were subjected to an analysis of study, 15 accountants were randomly selected from each of the four leadership style accountants). Each accountant was asked to rate the degree to which their variance.

A) Ata .05, there is sufficient evidence of differences among the substandard work scale means for the four leadership styles. B) Ata .05, nothing can be said. C) Ata -05, there is insufficient evidence of differences among the substandard work scale means for the four leadership styles. D) At ? .05, there is no evidence of interaction. 10) The owner of a local nightclub has recently surveyed a random sample of n- 250 customers of the club. She would now like to determine whether or not the mean age of her customers is greater than 30. If so, she plans to alter the entertainment to appeal to an older crowd. If not, no entertainment changes will be made. Suppose she found that the sample mean was 30.45 years ar the sample standard deviation was 5 years. If she wants to have a level of significance at 0.01 wh lusion can she make? There is not sufficient evidence that the mean age of her customers is greater than 30 There is sufficient evidence that the mean age of her customers is not greater than 30. C) There is not sufficient evidence that the mean age of her customers is not greater than 30. D) There is sufficient evidence that the mean age of her customers is greater than 30.Explanation / Answer
p- value is less than 0.05 so we reject Ho and conclude that there is significant difference in mean work scale score of four leadership styles.
Option A is correct.
