The average female bobcat weight about 9.6 kg. Let's assume μ = 9.6 and σ = 1.35kg. a) Calculate Pr{Y > 10.3} b) Now assume you have a sample of n = 26 male bobcats. Calculate Pr{ Ȳ > 10.3}. c) Which probability is lower? Why?

part C and D

Ray is an airline inspector and completed an average of u = 10 inspections each day. The distribution of daily inspections is approximately normal with a standard deviation of o 2 inspections. For a randomly selected day, what is the probability that Ray completes less than 9 inspections? a) 0.3413 O b) 0.1587 c) 0.3085 d) 0.6915

Find the probability of z occurring in the indicated region. z = 0.67 z = 1.89 a) Based on the diagram above my probability should be less than b) The probability statement is : P ( 0.67 ✓ <= ✔ z = ✔ = ✔ 0.5000 or 50%? <= ✔ 1.89 ✓)=P( z = ✔ <= ✔ 1.89 c) The probability 0.2221 x can also be considered 22.21 *% which is less than 0.5000 or 50% of the curve. ) P( 2 ✓ = <= ✔ 0.67 = 0.2221
