lara31 [8.8K]

Hi there,

2400 + 1632 = 4032

3 * 192 = 576

4032 - 576 =>

3532 - 76 =>

3532 + 24 - 76 - 24

3556 - 100

3456

3456 / 576 => 6

Therefore, 6 hours of sprayer work

Hope this helps!

Sincerely,

The Mean Corporation's statisticians would like to construct a hypothesis test for the mean annual profit (μ) earned by health-d

Jobisdone [24]

Missing Part of Question

Juice that is opened. It is known that the annual profits earned by health-drink franchises has a population standard deviation of $8,700

........

Answer:

z = 1.157

Step-by-step explanation:

Given

Annual profit as calculated = $90,300.

H0: μ = 89,000

Ha: μ > 89,000

σ = 8700

n = 60

Calculate the test statistic (z) that corresponds to the sample and hypotheses.

Test statistic (z) is calculated by

z = (x - μ)/(σ/√n)

Where x = 90,300

μ = 89,000

σ = 8700

n = 60

z = (90,300 - 89,000)/(8700/√60)

z = 1.157443298866584

z = 1.157 ----- Approximated

Answer:

$\frac{4\sqrt{5} }{5}$

Step-by-step explanation:

$\frac{4\sqrt{6} }{\sqrt{30} } =\frac{\sqrt{30} *4*\sqrt{6} } \sqrt{30} {\sqrt{30} } \\\\$

$\frac{4\sqrt{6*30} }{30} =\frac{4*\sqrt{180} }{30} =\frac{4*\sqrt{36*5} }{30} = \\\\\frac{4*6\sqrt{5} }{6*5} =\frac{4\sqrt{5} }{5}$
