Answer:
[a]. check attachment.
[b]. It can not be said that the difference is ascribed to chance as P-value = 0.001 which is less than <<0.05. That is P-value = 0.001 <<0.05.
Step-by-step explanation:
Without mincing words let's dive straight into the solution to the question above.
[a]. The drawing showing the histogram of bacterial endotoxin levels is given in the attached picture.
KINDLY NOTE: The data is right-skewed.
[b]. ALLERGIC MEAN SE MEAN STDEV N
FALSE 1510 251 1789 251
TRUE 530 109 343 10
False - true = difference in a.
Hence, 80 = estimated difference.
For the difference, 95% CI = (434, 1527).
DF = 58, P-value = 0.001, and the T value = 3.59.
Therefore, It can not be said that the difference is ascribed to chance as P-value = 0.001 which is less than <<0.05. That is P-value = 0.001 <<0.05.
Answer:
<u>15 miles</u>
Step-by-step explanation:
The rectangular walking path has vertices at (-4,5), (1,5), (-4,-5) and (1,-5).
See the attached figure.
The length of the walking path = the perimeter of the rectangle
As shown, The rectangle has length of 10 units and width of 5 units
So, the perimeter = 2 ( length + width ) = 2(10+5) = 2 + 15 = 30 units
Given: 1 unit² = (1/4) mile²
so, 1 unit = √(1/4) mile = (1/2) mile
so, the the walking path = 30 units = 30 * 1/2 = 15 miles
So, the length of waking path = 15 miles
