(i) A sample consists of the following values: 10, 8, 6, 4 Determine the range of values within which the true value of the mean of the population has a 97.5% probability of lying. (ii) In order to increase accuracy a further four values are obtained. These are: 4.6, 6.8, 8, 9.5 With this extra information determine the range of values within which the mean value has a 97.5% probability of lying.
A credit score is a numerical value between 300 and 850 that measures a person's creditworthiness. Summary statistics and graphical display of credit scores for randomly selected 40 - 59 years old individuals from Texas, Pennsylvania, California, and Florida are shown below. Does average credit score differ by state? Statistics TX PA CA FL FL Sample Size 36 36 36 36 CA Mean 671.7 730.3 710.1 704.8 PA Standard Deviation 42.7 45.6 33.4 38.1 TX 550 600 650 . 1. The above charts show that on average, for this sample, credit scores in ...... 700 750 800 TX PA CA FL (choose one) tend to be lowest, and credit scores in TX PA CA FL (choose one) tend to be highest. 2. Formulate the appropriate hypotheses: Ho: Average credit score differs does not differ (choose one) by state. Ha: Average credit score differs does not differ (choose one) by state. 3. The distributions of the credit scores show quite a bit of variability. Should we be concerned when applying the ANOVA procedure? Why or why not?…
