Weights of the vegetables in a field are normally distributed. From a sample Carl Cornfield determines the mean weight of a box

IceJOKER [234]

Answer:

P(X≤164) = 0.16

Step-by-step explanation:

We are given that the weights of vegetables are normally distributed with mean $\mu$ = 172

Standard deviation, $\sigma$ = 8

We need to calculate P(X≤164) we will use Z score to calculate this,

Z= $\frac{X-\mu}{\sigma}$ = $\frac{164-172}{8}$

Z≤ -1

P(Z≤ -1) = 0.1587 (Using normal distribution table)

Rounding to nearest hundredth = 0.16

Now 0.5-0.34 = <u>0.16</u> or <u>16%</u>

Find a 99% confidence interval for the previous problem.A) ($99,271.44, $100,728.56)B) ($99,242.00, $100,758.01)C) ($99.996.46,

Mamont248 [21]

95% confidence interval is given by

x - 2D , and x+ 2D

For 99% confidence interval is

x - 3D , and x + 3D

x = 100000

D = 2000

Then calculate

100000 - 3•2000= 94000

and

100000 + 3•2000= 106000

Now find √D = 44.72

Then interval is

100000 - 44.72 ,. And. 100000 + 44.72

99,956 lower limit and. 100472 upper limit

Then we see that theres only one interval ,

that is between thes 2 limits

ANSWER Is OPTION C) ) ($99.996.46, $100,003.55)
