Answer:

2=100

3=100

4=80

5=80

6=100

7=80

8=100

Step-by-step explanation:

If 1 is equal to 80 than 2 must be equal to 100. 180-80=100.

Using the z rule you can find that 2 and 4 are equivalent and 1 and 4 are equivalent. You can also find that 1 and 5 are adjacent using the z rule (add up to 180). So 5 is is 80. Using the same steps as on the a line you can find 6,7,8.

If seven seeds are planted, find the probability of having exactly six seeds germinate

vazorg [7]

Answer: P(6/7G) = 729⁄16384 = 0.044

The probability of having exactly six seeds germinate is 0.044

Complete Question:

A certain seed has 75% germination rate. Of seven seeds are planted, find the probability of having exactly six seeds germinate.

Step-by-step explanation:

The probability that a seed will germinate is

P(G) = 0.75

The probability that a seed will not germinate is

P(G') = 1-0.75 = 0.25

Therefore the probability that only 6 will germinate can be written as;

P(6/7G) = the probability that 6 seed germinate × the probability that one seed will not geminate

P(6/7G ) =[ P(G)]^6 ×[ P(G')]

P(6/7G) = 0.75^6 × 0.25

P(6/7G) = 729⁄16384 = 0.044

a random sample of n=24 data from a normal distribution with unkown variance produced x=42.5 and s=26 what is the 95 confidence

iogann1982 [59]

Answer:

95% of confidence intervals are

(31.5215 , 53.4785)

Step-by-step explanation:

Explanation:-

Given sample size 'n' =24

Mean of the sample x⁻ = 42.5

Standard deviation of the sample 'S' = 26

95% of confidence intervals are determined by

$(x^{-} - t_{0.05} \frac{S}{\sqrt{n} } , x^{-} + t_{0.05} \frac{S}{\sqrt{n} })$

Degrees of freedom

ν =n-1 = 24-1 =23

$t_{0.05} = 2.0686$

95% of confidence intervals are

$(42.5 - 2.0686 \frac{26}{\sqrt{24} } , 42.5+ 2.0686 \frac{26}{\sqrt{24} })$

( 42.5 -10.9785 ,42.5 +10.9785)

(31.5215 , 53.4785)
