Suppose that the random variable x is normally distributed with mean = 500 and standard deviation
Question:
Suppose that the random variable x is normally distributed with mean μ = 500 and standard deviation σ = 100. For each of the following, use the normal table to find the needed value k. In each case, draw a sketch.
a. P(x ≥ k) = .025
b. P(x ≥ k) = .05
c. P(x < k) = .025
d. P(x ≤ k) = .015
e. P(x < k) = .985
f. P(x > k) = .95
g. P(x ≤ k) = .975
h. P(x ≥ k) = .0228
i. P(x > k) = .9772

I have been teaching college students in various subjects for 9 years now. Besides, I have been tutoring online with several tutoring companies from 2010 to date. The 9 years of experience as a tutor has enabled me to develop multiple tutoring skills and see thousands of students excel in their education and in life after school which gives me much pleasure. I have assisted students in essay writing and in doing academic research and this has helped me be well versed with the various writing styles such as APA, MLA, Chicago/ Turabian, Harvard. I am always ready to handle work at any hour and in any way as students specify. In my tutoring journey, excellence has always been my guiding standard.
