Naomi weighed 50 patients for a medical study using a scale that measures to the nearest whole pound. She then calculated the me
1 answer:
99.7 percentage of the data lies between 140 and 212 pounds when the distribution of the standard deviation is normal.
<h3>What is standard deviation?</h3>Any given quantity, which is used to express that how many observations differ from others in the total observations of a data, is referred to as standard deviation. It is represented by σ.
To calculate the percentage of data lying between the given values, we will use the formula of empirical method and the given information to compute as under,
Solving further,
Hence, the significance upon the standard deviation of data weighted by Naomi is as aforementioned.

Answer:
From zero to 33 boats option B would be best
Explanation:
Assuming the first alternative (A)is 250,000 fixed and 500 per boat
second (B) 2,500 cost per boat
and third (C) 50,000 fixed and 1,000 cost per boat
We want' to know at which level B would be the best option
we want to know when alternative C or A have a cost of 2,500 or lower:
A:
Q = 125
From this point, as fixed cost will be distribute among more units, the cost will decrease meaking C better than B
C:
Q = 33.33
From this point, as fixed cost will be distribute among more units, the cost will decrease meaking A better than B
From zero to 33 boats option B would be the best of the three options
