1. In basic statistics, the three measures of central tendency are mean, median and mode. 2. In basic statistics, the three measures of dispersion are range, variance, and standard deviation. 3. Degrees of freedom are first determined by determining which type of calculation you will be doing that involves degrees of freedom. Likewise, degrees of freedom are calculated differently depending on the type of test you are performing, which is then determined by the number of samples that you have

Question 1 # sold | P(x) | 0 | 0.1 | 1 | 0.11 | 2 | 0.2 | 3 | 0.23 | 4 | 0.3 | 5 | 0.06 | Question 2: The average rate of occurrence of accidents was 8.15 per week. A) during that time, what is the probability of getting less than 3 accidents a week? Use poisson for this question. Since it is less that 3 accidents, x = 0,1,2 (Px=o) = [(8.15^0) (e^8.15)] / 0! = 0.00288735. (Px=1) = [(8.15^1) (e^8.15)] / 1! = 0.002353193. (Px=2) = [(8.15^2) (e^8.15)] / 2! = 0.009589362. Add all these

$45.63. Next we must calculate the sample standard deviation. The sample standard deviation for the lunch sample is 3.3793 and the sample standard deviation for the dinner sample is 6.9587. Next we must determine the standard error of the mean. In order to calculate the standard error of the mean, we must divide the sample standard deviation by the square root of the sample size. The standard error of the mean for the lunch sample is 0.6759 and the standard error of the mean for the dinner sample is

The assumption that was met in this study is the normal distribution. 5. Compare the 3 months and 6 months t ratios for the variable Exercise from Table 3.

PROBLEM 1: Old City Photographics a) To determine if the process is supply or demand constrained, we need to compute the implied utilization of each operation. Implied utilization is: (100% x 13 jobs/hr x 2min/job) / (60min/hr) = 0.43 for “Process Film” ((37%+19%) x 13 jobs/hr x 5min/job) / (60min/hr) = 0.61 for “Scan Film” ((44%+37%) x 13 jobs/hr x 4min/job) / (60min/hr) = 0.70 for “Take 6x4 Prints” (19% x 13 jobs/hr x 10min/job) / (60min/hr) = 0.41 for “Make Contact Print”

ONE WAY ANOVA One-way analysis of variance (abbreviated one-way ANOVA) is a technique used to compare means of two or more samples (using the F distribution). This technique can be used only for numerical data. The ANOVA tests the null hypothesis that samples in two or more groups are drawn from populations with the same mean values. To do this, two estimates are made of the population variance. These estimates rely on various assumptions. The ANOVA produces an F-statistic, the ratio of the variance

of appropriate standard statistical models and methods of statistical inference. (1) Standard models (binomial, Poisson, normal) are described. Application of these models to confidence interval estimation and parametric hypothesis testing are also described, including two-sample situations when the purpose is to compare two (or more) populations with respect to their means or variances. (2) Non-parametric inference tests are also described in cases where the data sample distribution is not compatible
