Score for Question 1: ___ of 6 points) 1. The earth makes a full rotation in 24 hours. Jupiter takes approximately 58 days, 15 h

Makovka662 [10]

we know that

1 day is equal to --------------> 24 hours

1 minute is equal to--------> 1/60 hours

then

convert (58 days, 15 h, and 30 min) to hours

= [58*24+15+30*(1/60)]

=[1,392+15+0.5]

=1,407.5 hours

therefore

the answer is

Jupiter complete a full rotation in 1,407.5 hours

Suppose a sample of 30 employees from the manufacturing industry showed a sample mean of $23.89 per hour. Assume a population st

timama [110]

Answer:

The p-value of the test is 0.1212.

Step-by-step explanation:

A one sample z-test can be performed to determine whether the mean hourly wage differs from the reported mean of $24.57 for the goods-producing industries.

The hypothesis is defined as:

H₀: The mean hourly wage is same as the reported mean of $24.57 for the goods-producing industries, i.e. μ = $24.57.

Hₐ: The mean hourly wage differs from the reported mean of $24.57 for the goods-producing industries, i.e. μ ≠ $24.57.

The information provided is:

$\bar x=\$23.89\\n=30\\\sigma=\$2.40$

Compute the test statistic as follows:

$z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}=\frac{23.89-24.57}{2.40/\sqrt{30}}=-1.55$

The test statistic value is, z = -1.55.

Compute the p-value of the test as follows:

$p-value=2\times P(Z$

*Use a z-table for the probability.

Thus, the p-value of the test is 0.1212.

Liam's bottle had 2 1/2 cups of juice in it. He drank 1/3 of the juice in his bottle. How many cups of juice did Liam drink?

myrzilka [38]

You basically have to do 2 1/2 times 1/3....

$2 \frac{1}{2} * \frac{1}{3} = \frac{5}{2} * \frac{1}{3} = \frac{5*1}{2*3} = \frac{5}{6} \ \textless \ -answer$
