Answer:
The median of the data is 5 :)
Step-by-step explanation:
The answer is C. Systemic random sampling.
By definition, systemic random sampling is a sampling technique where the respondents are selected according to a <em>random starting point </em>(this alone shows that the answer is C.) The researcher then chooses the sample interval, which is the difference between two consecutive numbers in the progression.
In this case, the starting point is 8 and the sample interval is 10.
The answer is C.
Answer: 6 1/5 miles
Step-by-step explanation:
Here's the complete question:
On Tuesday, Stacy rode her bicycle 1 3/4 miles from her house to the supermarket. She walked 1/4 of a mile while at the supermarket. She rode her bicycle a different way home that was 2 1/5 miles long. How many miles did Stacy ride her bicycle on Tuesday.
The number of miles that Stacy ride her bicycle on Tuesday will be the addition of her distance from her house to the supermarket and back to her house from the supermarket. This will be:
= Distance to supermarket = 1¾ + ¼ = 2 miles
Distance from supermarket = 2 + 2 1/5 = 4 1/5 miles
Total distance = 2 + 4 1/5 = 6 1/5 miles
The answer is given by the empirical rule, 68%.
