Flavia was curious if a sample first quartile (or Q_1Q 1 Q, start subscript, 1, end subscript) was an unbiased estimator of a population first quartile. She started with a large normally distributed population of test scores whose first quartile was Q_1=70Q 1 =70Q, start subscript, 1, end subscript, equals, 70 points. She then took a random sample of 666 tests and calculated the first quartile of the sample. She replaced those tests and repeated this process for a total of 505050 trials. Her results are summarized in the dotplot below, where each dot represents the first quartile from a sample of 6 tests.

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

the highest percentage for deaths in construction from highest to lowest is as follows: falls, struck by objects, electrocution, and caught-in/between. these four are collectively known as fatal four.

in the case of falls, the type that is responsible for the overall highest death in the category is falls from roofs.
