Answer:

$58,600

Step-by-step explanation:

Data provided in the question:

Commission on Sales upto and including $40,000 = 5%

Commission on Sales above $40,000 = 10%

Total commission = $3,860

Now,

For sales of $40,000

maximum commission = 5% of $40,000

= $2,000

Since the commission received is greater than $2,000

Therefore,

The value of s is greater than $40,000

Thus

Amount qualifying for 10% commission = s - $40,000

therefore,

Total commission = $2,000 + 10% of (s - $40,000)

or

$3,860 = $2,000 + 0.10 × (s - $40,000)

or

$1,860 = 0.10 × (s - $40,000)

or

s - $40,000 = $18,600

or

s = $18,600 + $40,000

or

s = $58,600

The administrator of a nursing home would like to do a time-and-motion study of staff time spend per day performing nonemergency

WINSTONCH [101]

Answer:

32 days must be sampled to test the proposed hypothesis.

Step-by-step explanation:

Consider the provided information.

The average number of person-hours per day spent on these task was $\mu_0=16$ .

The actual value of μ is 12 hours or less i.e μ=12

She wants a test having α=0.05

The probability of a type II error of at most β=0.10 and σ=7.64.

δ = μ-μ0

= 12-16

= -4

Now use the formula for calculating the sample size:

$N=\frac{(Z_{\alpha}+Z_{\beta})^2\sigma^2}{\delta^2}$

Substitute the respective values.

$N=\frac{(Z_{0.05}+Z_{0.1})^2(7.64)^2}{(-4)^2}$

$N=\frac{(1.6449+1.2816)^2(7.64)^2}{16}$

$N=31.2437958482\approx 32$

Hence, 32 days must be sampled to test the proposed hypothesis.
