Section 5.1: Normal Distributions                                         X~ N(center, st.dev.)   Example 1: Find the specified areas for a standard normal density.   The area below z = 0.8 The area above = 1.2   c. The area between z = -1 and z = 2

Let Z be the standard normal variable. Find the values of z if z satisfies the following: P(-z < Z < z) = 0.8502 A) 1.81 B) 0.24 C) 1.44 D) -0.71 E) 0.79

1.)Find the z-score corresponding to the given area of the normal curve with the following given values: a.) Area to the right of -z is .6736 b.) Area to the left of z is .7518

A random variable x is best described by a normal distribution with μ = 30 and o =10. Find the z-score that corresponds to the value x = 35. A) 5 B) 0.5 C) 1/6 D) 3.5

A researcher wants to see if there is a difference in APGAR scores of newborns depending on whether the mother smoked during pregnancy or not. She collects data and analyzes the results using SPSS. What is the correct way to report the results in APA style?   Question 23 options:   t(58) = 3.288, p>.05   t(58) = 3.288, p= .002   t(26.5) = 3.278, p<.05   t(26.5) =3.278, p=.003

Consider a normal distribution curve where 70-th percentile is at 12 and the 45-th percentile is at 7. Use this information to find the mean, μ, and the standard deviation, o, of the distribution. a) με b) σ =

A newspaper article reported that 320 people in one state were surveyed and 80% were opposed to a recent court decision. The same article reported that a similar survey of 510 people in another state indicated opposition by only 30%. Construct a 99% confidence interval of the difference in population proportions based on the data. The 99% confidence interval of the difference in population proportions is ( (Round to four decimal places as needed.)
