The sample mean = 2.50 and the sample standard deviation = 0.8302. The distribution can be written as X ~ U(1.5, 4.5). What is P(x < 3.5|x < 4)? (Enter an exact number as an integer, fraction, or decimal.)
Added by Viviana R.
Step 1
5 and x = 4 using the formula z = (x - mean) / standard deviation. For x = 3.5: z = (3.5 - 2.50) / 0.8302 = 1.20 For x = 4: z = (4 - 2.50) / 0.8302 = 1.80 Show more…
