Which of the following was not among the early attempts to determine Earth’s age?

You need to purchase both a computer and a television. You find both items on a super-one-time-only sale, but only have enough money to purchase one. You need to figure out which is the better deal. The computer costs $570. The average cost for this computer at all the stores you’ve looked at is $699, with a standard deviation of $30. The television costs $460, with an average cost normally of $580, with a standard deviation of $25. Based on these numbers which item is the better deal? Use data to support your answer.

For each variable listed below, indicate if the variable is nominal, ordinal, interval, or ratio.  Type of exercise class (with the values 1 = beginning, 2 = intermediate, 3 = advanced) [class] Number of correct answers on a 10-question quiz. [quiz] Time on task measured with the following scale: 0-10 minutes, 11-20 minutes, 21-30 minutes, 31-40 minutes, 41-50 minutes [activity] Study preference (1= no music, 2 = music) [music]

Use the scores below to calculate the mean. **Report your answer to 4 decimal places. [a], [b], [c], [d], [f], [g], [h]

Construct a frequency distribution for the following scores: 5  3  3  2  4  3  4  3  3  5  4  1 Based on the frequency distribution, what is: The frequency for a score of 1 [f] The relative frequency for a score of 1 [rf] The cumulative frequency for a score of 1 [cf] The cumulative relative frequency for the score of 1 [crf] **To receive credit for this problem you will need to show your work. At the end of the exam you will be asked to upload a picture of your work.

You need to purchase both a computer and a television. You find both items on a super-one-time-only sale, but only have enough money to purchase one. You need to figure out which is the better deal. The computer costs $300. The average cost for this computer at all the stores you’ve looked at is $699, with a standard deviation of $35. The television costs $275, with an average cost normally of $589, with a standard deviation of $25. Based on these numbers which item is the better deal? Use data to support your answer.

For each variable listed below indicate the most appropriate measure of central tendency to use to characterize the variable: Major in college: [Major] Age (measured in years): [Age] Starbuck’s coffee sizes (short = 8 oz; tall = 12 oz; grande = 16 oz; venti = 20 oz): [coffee]

For each variable listed below, indicate if the variable is nominal, ordinal, interval, or ratio.  Drink size (small = 8 oz, medium = 12 oz, large = 20 oz, extra large = 32 oz) [drink] Family size (number of people in a person’s family) [family] Preference for a digital or analog watch [watch] Time on task measured with the following values:  0-10 minutes, 11-20 minutes, 21-30 minutes, 31-40 minutes, 41-50 minutes. [activity]

If you wanted to create a graph for the variable age (measured in years) that showed the individual frequencies of each score and the shape of the distribution, but you were limited on space and were unable to include a frequency histogram, what graph would be most appropriate?
