Use this data in the problem below. Follow the steps carefully. Round to the nearest tenth. Lot 1: Week 1: 600 Week 2: 300 Week
Dafna11 [192]

Answer:

Step-by-step explanation:

The given data set is:

Week 1: 600

Week 2: 300

Week 3: 500

Week 4: 900

The following are the steps to find the standard deviation:

Step 1. Jim enters the data and calculates the average or mean.

Mean=\frac{600+300+500+900}{4}=\frac{2300}{4}=575

Step 2. Jim calculates the deviation from the mean by subtracting the mean from each value.

Data value (x)                                                             x-{\overline{x}}

600                                                                           25

300                                                                         -275

500                                                                         -75

900                                                                          325

Step 3. Jim squares each deviation to remove negative signs.

Data value (x)                                                           (x-{\overline{x}})^2

600                                                                       625

300                                                                    75625

500                                                                      5625

900                                                                   105625

Step 4. Jim sums the squares of each deviation and divides by the count for the variance.

Variance=\frac{625+75625+5625+105625}{4}=46875

Step 5.Jim takes the square root of the variance to find the standard deviation.

Standard deviation=\sqrt{46875}=216.50
