Michael Short 803781208 Lab Week 9 Teen Texting Question 1 a. n=10 a. The sample proportion is about .03 away from the assumed population proportion. n=100 a. The sample proportion is about .008 away from the assumed population proportion n=1000 a. The sample proportion is about .0049 away from the assumed population proportion b. All three of these simulations are nearly normally distributed, unimodal, with centers around .2. The actual centers can be found by looking at the graphs below. Mean and standard deviation are also shown in the tables below. c. n=10 (-.2, +.3), n=100 (-.2, +.3), n=1000(-.2, +.4) d. n=10 (+-.209), n=100 (+-.04), n=1000 (+-.0209) e. As the sample size increases the standard deviation decreases, because the sample proportions are centered more around the true population proportion causing the margin of error to be less. N=10 N=100
