Coopers & Lybrand surveyed 210 chief executives of fast-growing small companies. Only 51% of these executives had a manageme

densk [106]

Answer:

92% Of confidence intervals to estimate the proportion of all fast-growing small companies that have a management succession plan.

(0.46154 , 0.558)

Step-by-step explanation:

Given sample size 'n' = 210

The sample proportion 'p' = 51% = 0.51

Confidence intervals are determined by

$(p^{-} - z_{\alpha } \sqrt{\frac{p^{-} (1-p^{-} }{n} } , p^{-} +Z_{\alpha } \sqrt{\frac{p^{-} (1-p^{-} )}{n } } )$

The 92% of z-score value

$Z_{\frac{\alpha }{2} } = Z_{\frac{0.08}{2} } = Z_{0.04} = 1.405$

92% Of confidence intervals to estimate the proportion of all fast-growing small companies that have a management succession plan.

$(0.51 - 1.405 \sqrt{\frac{0.51 (1-0.51 }{210} } , 0.51 +1.405 \sqrt{\frac{0.51 (1-0.51)}{210 } } )$

on calculation , we get

(0.51-0.048 , 0.51 + 0.048)

(0.46154 , 0.558)

Final answer:-

92% Of confidence intervals to estimate the proportion of all fast-growing small companies that have a management succession plan.

(0.46154 , 0.558)

andreev551 [17]

Answer:

{(1, 6), (2, 12), (3, 18), (4, 24)}

Step-by-step explanation:

We are given that ...

(packages, balls) = (1, 6)

Multiplying by 2, 3, and 4, we find the set of ordered pairs to be ...

{(1, 6), (2, 12), (3, 18), (4, 24)}

Factor p 2 + 18p + 32.

zhenek [66]

The correct factorization is (p + 16)(p + 2).

You can find this by looking for factors of the final number that add up to the middle number. Factors of the final number are listed below:

1 * 32

-1 * -32

2 * 16

-2 * -16

4 * 8

-4 * -8

Now you select the one that adds to 18, which would be the highlighted 2 and 16. Now we use these in parenthesis with a p + in the front of it.

(p + 2)(p + 16)

This will be the correct factored form.
