Could the graph represent a normal curve? Select all that apply. A. No, because the mean, median, and mode are equal. B. Yes, because the graph may not satisfy all of the criteria for a normal curve, but it satisfies at least one of the criteria. C. No, because the graph has a single peak. D. No, because the graph is symmetric about its mean. E. No, because the graph is always greater than or equal to zero. F. No, because the graph is not symmetric about its mean. G. No, because the graph is not always greater than or equal to zero. H. No, because the highest point of the graph occurs at the mean. 1. No, because the graph has multiple peaks. J. Yes, because the graph satisfies all of the criteria for a normal curve.

The results: A. Are, or B. Are not   significantly: A. High, or B. Low   so there: A. is, or B. is not

1. The two plots have similar distrubutions. Are the distrubutions skewed left, approximtly symmetric, or skewed right? 2. Which is greater, the mean or the median, within each plot? Why does this make snese, gicen the type of distrubution you identified in the first part? 3. The population has drastically declined over recent years. Does the data show a difference in bee prefrence towards high quality hives versus how quality hives? Usse statistical evidennce to support your response.

Part 2. Complete the following statements. A) The cumulative enrolment is the enrolment of the intervals smaller than the interval in question or equal to the latter. The graph of cumulative enrolment is represented by a function in B) The average, median and mode are three measures of of the C) The term refers to any data that deviates disproportionately from others. D) When the residual values are zero, then the correlation is called

5. Which of the following is the assumption that the best way to describe the pattern of data is using a straight line? homoscedasticity   normality   linearity   restriction of range

The mean number of sick days an employee takes per year is believed to be about 10.5. Members of a personnel department do not believe this figure. They randomly survey ten employees. The number of sick days they took for the past year are as follows: 12; 4; 15; 3; 11; 8; 6; 8; 2; 9. Let x = the number of sick days they took for the past year. Should the personnel team believe that the mean number is ten?
