Answer:
The probability that Jeannie will miss her flight because her total time for catching her plane exceeds one hour is 0.0026.
Jeannie should leave her office 55 minutes early.
Step-by-step explanation:
Let <em>X</em> = time it requires Jeannie to catch her plane.
The random variable <em>X</em> is normally distributed, .
Compute the probability that Jeannie will miss her flight because her total time for catching her plane exceeds one hour as follows:
The probability that Jeannie will miss her flight because her total time for catching her plane exceeds one hour is 0.0026.
Now, it is provided that Jeannie has 96% chance of catching her flight if she reaches under <em>x</em> minutes.
That is, P (X < x) = 0.96.
Compute the value of <em>x</em> as follows:
**Use the <em>z</em>-table to compute the value of <em>z</em>.
The value of <em>z</em> is 1.751.
Compute the value of <em>x</em> as follows:
Thus, Jeannie should leave her office 55 minutes early.
Upper Tolerance
Remark
The 11/16 is the only thing that will be affected. The three won't go up or down when we add 1/64 so we should just work with the 11/16. We need only add 11/16 and 1/64 together to see what the upper range is. Later on we can add 3 into the mix.
Solution
<u>Upper Limit</u>
Now change the 11/16 into 64. Multiply numerator and denominator or 11/16 by 4
Which results in
With a final result for the fractions of 45/64
So the upper tolerance = 3 45/64
<u>Lower Tolerance</u>
Just follow the same steps as you did for the upper tolerance except you subtract 1/64 like this.
Your answer should be 3 and 43/64
