Answer with explanation:
The Curve given here is a probability density curve for a continuous random variable.
Area under the entire region of the curve = 1
Using the Standard normal table to obtain area occupied when Z values are given
Area of the normal curve, when ,Z =0.88, is =0.8106
Area occupied by normal curve ,when Z= -1.26, is =0.1038
So, Area of shaded Region
Option D:→ 0.7068
I used one of the statistical functions on my trusty TI-83 Plus calculator:
normcdf(-1.26, 0.88) = 0.707
Note that this is, as expected, between 0 and 1.
B. 800 signs
C. 1,000 signs
D. 1,500 signs
Blaine could make approximately 650 signs in forty hours.
Calculate the working hours
Blaine needs 14 hours to set up his work station. So, out of the total 40 hours, he will have
=> 40 - 14 = 26 hours to actually work on making signs.
Calculate the minimum number of signs he can make
If Blaine makes 16 signs per hour, then in 26 hours, he will make a minimum of
=> 16 * 26 = 416 signs.
Calculate the maximum number of signs he can make
If Blaine makes 23 signs per hour, then in 26 hours, he will make a maximum of
23 * 26 = 598 signs.
Calculate the average number of signs he can make
To get a more reasonable estimate, we take the average of the minimum and maximum number of signs:
Average = (Minimum + Maximum) / 2
= (416 + 598) / 2 = 650 signs.
Hence the correct option is (a).
