# Statistics questions 2

The questions are structured as multiple answers, multiple choice, fill in the blank(s), true-false, or so-called hot spots, which require you to click on an area of an image to answer a question. Because grading of this assignment is automated, it is important in cases of fill-in-the-blank(s) questions that you spell your answers correctly or it will be scored incorrect. Also, when you have to generate a response to fill a blank, do not include any extra information other than what is exactly called for by the question (for example, if the answer is the number “1110”, typing in “1,100” will be scored as incorrect by Blackboard because it includes an unnecessary comma; an unnecessary space(“1 100”) would similarly be marked incorrect. If we see instances like this we will change them to correct, but we do not always catch these issues nor do students themselves, so best to avoid them altogether!

If the question requires computation, do the calculations and then give or select the correct values using the following rule:

Keep at least 4 decimal places at intermediate steps of a calculation, and round your final answer to 2 decimal places, unless otherwise noted.

For example:

(67.3 ÷ 3.456) ÷ 2 x 15 = (19.4734) ÷ 2 x 15 = 9.7367 x 15 = 146.0505, this is the final answer so round to two decimal places to get 146.05.

final calculated value of 16.6667 would become 16.67 after rounding

14.3112 would become 14.31

26.8973 would become 26.90

4.6251 would become 4.63 (In contrast to what Howell says, always round up with a value of 5 even if it produces an odd rather than an even final number as in this example.)

Failure to follow this rule, like misspellings, could lead to automated scoring errors.

(In the course notes for Module 7, probabilities such .678934 are instead rounded to four decimal places, so the correct way to report the aforementioned probability is .6789. You do not need to add zeros to fill four decimal places, e.g., do not change .25 to .2500)
