a. As 0.54 lies left to 0.58 (mean of the sampling distribtution), Probability that proportion greater than 0.54 is greater than 50% (area to the right of 0.54 is greater tha 50% as area to the right of 0.58 is 50%)
b. P(p>= 0.54)
= 0.874 rounded)

7.3.42 probability that 25% or more of our sample will be bving in poverty Complete parts (a) and (b) below. a. Before doing any calculations, determine whether this probability is greater than 50% or less than 50%. Why? The answer Should be less than 50%, because 0.25 is greater than the population proportion of 021and because the sampling distreut n is app onately Normal mo answer ano ad be gea er man 50% because the resulting z-score will bo postive...
How do I solve the final part? %x) 7.3.41 Question Help A recent study reported that 58% of the children in a particular community were overweight or obese. Suppose a random sample of 200 public school children is taken from this community. Assume the sample was taken in such a way that the conditions for using the Central Limit Theorem are met. We are interested in finding the probability that the proportion of overweight/obese children in the sample will be...
PU Math 80 - Statistics Central Limit Theorem for Sample Proportions Handout 5.2 2 ES school 0.5. schools face an ongoing challenge: as students get closer to high school graduation, their enthusiasm for school falls. A Gallup poll in June 2017 has discovered that fifth graders are most engaged with school, while 11th graders are least. The latest Gallup poll showed that only 32% of 11th graders are engaged in school. Assume this value represents the population proportion. Suppose we...
