      Use the top row to determine the second decimal for z. Here, with Z of 2.5, the second decimal is 0 so we use the second column, which has a .00 at the top. You should find the value 0.4938. What does this number represent? It is the area under the normal curve from 0 out to 2.5: that is, it measures P(0 < z < 2.5). It is NOT P(Z > 2.5). But ...

      (a) The house that sold for $350 thousand has 28 out of 35 house prices below it, so it is at the 80th percentile. The z-score for $350 thousand is (350 – 260.8)/145.6 = 0.61, which is 0.61 standard deviations above the mean house price. (b) $220 thousand—the median is the best measure of the center of a skewed distribution.

Prob(z < 1.5) 0.9332 In a certain microwave oven on the high power setting, the time it takes a randomly chosen kernel of popcorn to pop is normally distributed with a mean of 140 seconds and a standard deviation of 25 seconds. What percentage of the kernels will fail to pop if the popcorn is ...

      Now, we can compute the z-score and get z = (0.65 – 0.75) / 0.0433 = -2.31. Then, we use a z-table to find P(Z < -2.31) = 0.0104. 38. B Note that we are taking a random sample of 143 adult males. Since this sample size is larger than 30, we can use the Central Limit Theorem and conclude that average weight is approximately normally ...

      From the Z table, we see that 0.5 – 0.025 = 0.475 corresponds to a Z-value of 1.96. Between what two values of Z (symmetrically distributed around the mean) will 68.26% of all possible Z-values be contained? We look in the table for 0.6826/2 = 0.3413, which corresponds to a Z-value of 1.0. Here is how to answer all of these using Excel: 23 ...

      A half-space may be negated by just changing the sign on x,y,z,l, so the half-space table is just the disjunctive normal form representation of the domain. This representation has some shortcomings: it ignores points exactly on the surface (the inequality is strict), and more importantly, it does not easily support “holes” in a convex.

      So, how likely do you get a sample mean that exceeds 120 cm? Find the z score of 120 cm with respect to the normal distribution of the sample mean,. Look up the normal curve table and you will get 0.8749 (this is the size of the area to the left of z = 1.15). To answer the question, take 1 – 0.8749 = 0.1251. Question 5.
