A packet of vegetable seeds has a germination rate of
Doss [256]

N = number of seeds planted

P = probability of germination

K = number that germinated

Using probability calculation:
p(x = k) = (n k) x 0.90^K x 0.10^n-k


p(10) = (12 10) x 0.90^10 x 0.10^2

P(10) = 0.2310

A manufacturer knows that their items have a normally distributed lifespan, with a mean of 15 years, and standard deviation of 3
Gala2k [10]

Answer:

The probability that their mean life will be longer than 13 years = .9943 or 99.43%

Step-by-step explanation:

Given -

Mean (\nu  ) = 15 years

Standard deviation (\sigma  ) = 3.7 years

Sample size ( n ) =22

Let \overline{X} be the mean life of manufacturing items

the probability that their mean life will be longer than 13 years =

P(\overline{X}>  13) =  P(\frac{\overline{X} - \nu }{\frac{\sigma }{\sqrt{n}}}>  \frac{13 - 15 }{\frac{3.7}{\sqrt{22}}})       (Z =\frac{\overline{X} - \nu }{\frac{\sigma }{\sqrt{n}}})

                    =  P(Z> -2.53)

                    = 1 - P(Z <  -2.53)       Using Z table

                    = 1 - .0057

                    =  .9943
