Question
Use the applet below to select a random sample of 9 babies from the town. Assume μ = 3,500. Repeat many times to observe how the mean birth weights for the samples vary. Then answer the following question. Click to generate a random sample of the weights of 9 babies Population: babies born in town this year Average birth weight in grams: µ = 3500 Sample: 3271 3467 4015 3440 3451 3528 2901 3471 4244 Sample statistic: & = 3532 Sampling Distribution 3,000 3,100 3,200 3,300 3,400 3,500 3,600 3,700 3,800 3,900 4,000 Sample Means: 3704, 3663, 3548, 3398, 3494, 3513, 3503, 3818, 3492, 3447, 3550, 3271, 3542, 3589, 3491, 3532
