The risk of females experiencing an anxiety disorder during a given 12-month period is approximately 1 in 5. Suppose a researcher plans to take a random sample of females and monitor their anxiety over 12 months. Which probability distribution can be used to model the expected number of females in a sample experiencing an anxiety disorder within this period?

Answer #1

Since the females experiencing an anxiety disorder during a given 12-month period is approximately 1 in 5

that is p = 1/5 = 0.2

is independent and same for all cases

Hence we will use the binomial distribution to calculate probability distribution can be used to model the expected number of females in a sample experiencing an anxiety disorder within this period

    1.) Accrotime is a manufacturer of quartz crystal watches. Accrotime researchers have shown that the watches have an average life of 30 months before certain electronic components deteriorate, causing the watch to become unreliable. The standard deviation of watch lifetimes is 10 months, and the distribution of lifetimes is normal. (a) If Accrotime guarantees a full refund on any defective watch for 2 years after purchase, what percentage of total production will the company expect to replace? (b) If Accrotime...
