Step-by-step explanation:

<u>3,4,4,5,5,6,  </u>6,6  ,<u>6,7,9,12,14,15</u>

6,6 is the median but we only need I median. So 6 + 6 = 12, 12 divided 2 = 6.

3,4,<u>4,5,</u>5,6,  is the Q1 ( lower quartile ) and median of Q1, is 4,5. 4 + 5 = 9. 9 divided 2 = 4.5

6,7,<u>9,12,</u>14,15  is Q3 ( upper quartile) 9,12 is median but we only need one. So 9 + 12 =21. 21 divided 2 = 10.5

Nonamiya [84]

99% confidence limits for population proportion is:

CL = P +- Z * √(P*(1-P)/N))

Where:

P = sample proportion

Z = Z-score taken at 99% confidence = 2.575

N = sample size

Calculating for the values:<span>
P = 350/500 = 0.7 
N = 500 </span>

Substituting know values to the CL equation:

<span>CL = 0.7 +-  2.575* </span>√<span>(0.7*(1-0.7)/500))</span>

<span>CL = 0.647 , 0.753</span>

<span>
</span>

<span>Therefore confidence limits range from 0.647 to 0.753.</span>

Find the 25th term of the sequence -7,-22,-37.
Molodets [167]

Answer:

a₂₅ = - 367

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = - 22 - (- 7) = - 37 - (- 22) = - 15

This indicates the sequence is arithmetic with nth term

a_{n} = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 7 and d = - 15 , then

a₂₅ = - 7 + (24 × - 15) = - 7 - 360 = - 367
