A survey of 200 people was conducted to see if they smoke. The results are shown in the table. Male Female Total Smokes 87 74 161 Doesn't smoke | 22 17 39 Total 109 91 200 If a person is selected at random, what is the probability that the person is a male or a smoker? O 0.423 O 0.915 O 1.785 O correct answer is not given

4). Using the data in the question #2, construct a histogram and then construct a frequency polygon.

d). What is the pmf? 3) What is the median, ã ?

Determine Px and ox from the given parameters of the population and sample size. μ = 62, o = 24, n = 35 = ...

If you recieved the data set {9, 16, 10, 20, X} and you knew the median was 15, what could you say about X? O 10 < X < 18 OX = 14 O11 < X < 17 OX = 15 ONone of the above.

In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer.In the following data pairs, A represents birth rate and B represents death rate per 1000 resident population. The data are paired by counties in the Midwest. A random sample of 16 counties gave the following information. A: 12.5 13.2 12.6 12.1 11.4 11.1 14.2 15.1 B: 9.6 14.3 10.7 14.2 13.2 12.9 10.9 10.0 A: 12.5 12.3 13.1 15.8 10.3 12.7 11.1 15.7 B: 14.1 13.6 9.1 10.2 17.9 11.8 7.0 9.2

Part 4. 1. Examine the data set below that represents a sample. A.) the average of the sample; B.) the median of the enéchantion; C.) the mode of the sample; D. ) the minimum and maximum values; J.) the extent; F.) the first, second and third quartiles; G.) the interquartile interval; H.) the standard deviation of the sample; I.) The variance of the sample.
