Answer:

The proportion of callers is put on hold longer than 2.8 minutes is 0.3679

Explanation:

μ = 2.8 , λ = 1/2.8 ,

By the exponential distribution:

P(x>k) = exp(-λk)

          = exp(-2.8/2.8)

          = 0.3679

Therefore, The proportion of callers is put on hold longer than 2.8 minutes is 0.3679

Since  both coupons cancel each other.

In 10 years time a $100 will be the same to $70 today.

The 10-year rate, R, (10-year-rate) is  given as,

The rate is  1/10 in 100/70 =0.0357  or 3.57% per year.
