For #2 you would count how many where the red dashed line is! Which is 3! Then you would count where the blue dashed line is! Which is 4! So then it would be 4/3(4 over 3) For the slope! Hope this helps! :)

A farmer who grows genetically engineered corn is experiencing trouble with corn borers. A random check of 5,000 ears revealed t
Ivenika [448]

Answer:

Probability that an ear of corn selected at random will contain no borers is 0.4966.

Step-by-step explanation:

We are given that the distribution of the number of borers per ear approximated the Poisson distribution. The farmer counted 3,500 borers in the 5,000 ears.

Let X = <u><em>Number of borers per ear</em></u>

The probability distribution of the Poisson distribution is given by;

P(X=x) = \frac{e^{-\lambda }\times \lambda^{x}  }{x!}  ; x = 0,1,2,3,......

where, \lambda = parameter of this distribution and in our question it is proportion of bores in the total ears =  \frac{3500}{5000}  = 0.7

SO, X ~ Poisson(\lambda = 0.7)

Now, probability that an ear of corn selected at random will contain no borers is given by = P(X = 0)

                            P(X = 0)  =  \frac{e^{-0.7}\times 0.7^{0}  }{0!}

                                           =  e^{-0.7} = <u>0.4966</u>

Hence, the required probability is 0.4966.
