2) state in terms of x and draw the curve. Label with µ,σ, x. 3) standardize with new graph (turn x into z). 4) use table A or calculator: normalcdf (lowerbound, upperbound, µ, σ) 5) answer the question (remember if the distributions is approximately normal, you have an approximate probability). HW p 118 1 – 4, p 121 6 – 8 (not 7d)

Using calculator: The calculator code: 2nd DISTR 2 normalcdf (-0.12, 1.24) =0.4402707. Example 6. Suppose x is a normally distributed random variable with mean 10.2 and standard deviation 1.5. Find each of the following probabilities.. Draw normal curve and show the region bounded by the normal curve and the x values.

– a bar graph that displays a frequency distribution. Normal Distribution (bell curve) – a symmetric curve which indicates that the frequencies are concentrated around the center portion of the distribution. Example 1. The useful lives of 10,000 batteries are normally distributed. The mean useful life is 20 hours, and the SD is 4 hours. a.

This is the area to the left of –0.8. Because the total area under the curve is 1, the area lying to the right of –0.8 is 1-0.2119=0.7881. A. Standardize first, and we can get –1.7 < x < -0.2. Then, look at the table, the total area should be .4207 – .0446= .3761. D. We want …

When we enter the correct values, the calculator will draw us the bell-shaped curve for that, display it on the calculator screen, and show us exactly what we need. For the real-life application of this, if the vending machine company comes out, takes a sample, and their sample mean varies from what it’s supposed to be, the company knows that ...

Normal Curve. Although frequency distributions can be of any shape (unimodal, bimodal, peaked, flat, skewed, etc.), there is one pattern that occurs in such a wide variety of circumstances that it is regarded as the single most important type of data distribution in all of statistics.
