Determine the statistical significance of the two independent variables.  Assume a t-statistic with an absolute value greater than 2 is statistically significant. Show your work/thought process: a) Rotten Tomatoes ranking - b) With Seagal  -

The value(s) that occurs most frequently in a data set is called the

A Hospital record for a patient indicates the patient's assigned department, room location and number of days the patient was treated.  Classify each variable as qualitative or quantitative. A sample data table is listed below.   Department Room Location Days of Treatment Maternity A102 2  Cardiac G210 5 Orthopedic C309 3

For each problem, you must state the hypotheses, calculate the test statistic, and explain your decision. The following table reports the relationship between class standing and political orientation for a random sample of 267 college students.   a. The table is constructed assuming that class standing is the independent variable.  Please add %s in the appropriate position (columns or rows) to describe the pattern of the relationship. b. Is there a statistically significant relationship between these variables?

The number of trees planted in 10 housing estates are as follows. 108 42 81 53 70 53 44 75 140 137   i. Estimate the mean, median, 1st quartile and mode. ii. Plot the stem and leaf diagram.

Explain the relation between a population and a sample. What characteristics should a sample have to be representative of the population?

Q7: Compute 75th percentile for the data given               45, 32, 37, 46, 39, 36, 41, 48, 36.

Construct a box plot of a data set with a median of 50, a minimum value of 20, first quartile 42, IQR=29, and a maximum value of 90. What percentage of total data is between 42 and 71?

44 35 40 44 44 39 40 47 45 45 44 44 46 Find the mean cost. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. The mean cost is (Round to one decimal place as needed.) B. There is no mean cost. Does the mean represent the center of the data? A. The mean represents the center. B. The mean does not represent the center because it is the largest data value. C. The mean does not represent the center because it is not a data value. D. The mean does not represent the center because it is the smallest data value. OE. There is no mean cost. Find the median cost. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. The median cost is (Round to one decimal place as needed.) OB. There is no median cost. 40 0 0 0 O

Please help find the tstat. Thanks.
