Answer:
The z score for bolt of diameter 18.12 mm is 1.20.
Step-by-step explanation:
Let <em>X</em> = diameter of bolts.
It is provided that the random variable <em>X</em> follows a Normal distribution with mean, <em>μ</em> = 18 mm and standard deviation, <em>σ</em> = 0.10 mm.
A <em>z</em>-score is a standardized score, a numerical, that defines how far a data value from the mean.
The distribution of <em>z</em>-scores is defined by the Standard Normal distribution.
The formula to compute the <em>z</em>-score is:
The value of the diameter of a bolt is, <em>x</em> = 18.12 mm.
Compute the <em>z</em>-score for this value as follows:
Thus, the z score for bolt of diameter 18.12 mm is 1.20.

The hunter should purchase 3 ounces of seeds and 7 ounces of dried fruit to satisfy the scenario.
<u><em>Explanation</em></u>
the amount of seeds and
the amount of dried fruit.
As the hunter needs total 10 ounces of a snack mix , so the first equation will be..
Now the seeds cost $1.50 per ounce and the dried fruit costs $2.50 per ounce. And the mixture costs $2.20 per ounce, so the second equation will be:
According to the substitution method, we will isolate y from the first equation as
Now we will substitute this into the second equation in place of
Plugging this into the equation
, we will get...
So, the hunter should purchase 3 ounces of seeds and 7 ounces of dried fruit to satisfy the scenario.
Solution: For a positively skewed distribution with a mean of m=20, the most probable value for the median is less than 20.
<u>Explanation:</u>
We know that in a symmetric distribution, the relationship between mean, median and mode is:
In case of negatively skewed distribution, the relationship between mean,median and mode is:
In case of positively skewed distribution, the relationship between mean,median and mode is:
Therefore, for a positively skewed distribution with a mean of m = 20, the median would be less than Mean. Hence the probable value of median is less than 20
