Question

For these questions, refer to The Normal Distribution and Other Continuous Distributions Chapter (Ch 6. Section 2). (20 pts). Refer that X has a normal distribution of mean = ? and standard deviation = ?, then z has the standard normal distribution, where z = (X - ?)/ ? and use the cumulative Standardized Normal Distribution table in Appendix or D2L Statistics Tables. For the standard normal distribution, determine the following probabilities: a) P(z < 1.05) b) P (-1.96 < z < 1.96) For x has a normal distribution with mean = 100 and standard deviation = 10, determine the following probabilities: c) P( x < 85) d) P( x < 80 or x > 125)

Step 1

It is a normal distribution with a mean of 0 and a standard deviation of 1. We can convert any normal distribution to a standard normal distribution by subtracting the mean and dividing by the standard deviation. So, if X has a normal distribution with mean Q and Show more…

For these questions, refer to The Normal Distribution and Other Continuous Distributions Chapter (Ch 6. Section 2). (20 pts). Refer that X has a normal distribution of mean = μ and standard deviation = σ, then z has the standard normal distribution, where z = (X - μ)/ σ and use the cumulative Standardized Normal Distribution table in Appendix or D2L Statistics Tables. For the standard normal distribution, determine the following probabilities: a) P(z < 1.05) b) P (-1.96 < z < 1.96) For x has a normal distribution with mean = 100 and standard deviation = 10, determine the following probabilities: c) P( x < 85) d) P( x < 80 or x > 125)
