Successful hotel managers must have personality characteristics often thought of as feminine (such as "compassionate") as well as those often thought of as masculine (such as "forceful"). The Bem Sex-Role Inventory (BSRI) is a personality test that gives separate ratings for female and male stereotypes, both on a scale of 1 to 7. A sample of 148 male general mangers of three-star and four-star hotels had mean BSRI femininity score y = 5.29.The mean score for the general male population is μ = 5.19. Do hotel managers on the average differ significantly in femininity score from men in general? Assume that the standard deviation of scores in the population of all male hotel managers is the same as the σ = 0.78 for the adult male population. Follow the four-step process in your work.
In conducting a hypothesis test to see if there is evidence that the population mean is less than 220, using a .03 significance level what will be your critical value?
Summarize in words each of the following findings: The Tukey test was significant at .01 for two groups (A and E).
Construct a 99% confident interval for the standard deviation of the amount of vitamin B6 per pill.
His least squares regression line equation is: "assembly line output" = 1.03 + (5.1389 x Test Score). Which scatter plot has the graph of his line?
Choose one of the options below that explains what information is provided in the interval that is not in the significance test results:
The probability of each. If the answer cannot be calculated, enter zero (0) as your answer. Round to 4 decimal places otherwise. YES, you need, therefore, to look at the 5th decimal place.
Estimate the probability the store will gross over $850 a) At least 3 out of 5 business days.
Using symbols state hypotheses (H 0 and H 1 ) for two-tailed test. Sketch suitable distribution and locate critical region for a = 0.05.
If sample mean is M=44. Is this sufficient to demonstrate significant effect? Again assume a Two-tailed test with a=0.05.
In a recent study, a random sample of children in grades two through four showed a significant negative relationship between the amount of homework assigned and student attitudes. What is the explanatory variable and what is the response variable?
The Investment Research Institute reported in its Mutual Fund Fact Book that the number of mutual funds increased from 5725 in 1999 to 7977 in 2009. What is the geometric mean annual percent increase in the number of funds?
