UCF is a major Metropolitan University located in Orlando Florida. UCF is advertising their bachelor in Economics with the stati

ludmilkaskok [199]

Answer:

There is not enough evidence to suggest that mean starting salary of a graduate with a bachelor in economics is different from $48,500.

Step-by-step explanation:

In this case we need to test whether the mean starting salary of a graduate with a bachelor in economics is $48,500.

The information provided are:

$\bar x=\$43350\\s=\$15000\\n=50\\\alpha =0.01$

The hypothesis for the test can be defined as follows:

H₀: The mean starting salary of a graduate with a bachelor in economics is $48,500, i.e. μ = 48500.

Hₐ: The mean starting salary of a graduate with a bachelor in economics is different from $48,500, i.e. μ ≠ 48500.

As the population standard deviation is not known we will use a t-test for single mean.

Compute the test statistic value as follows:

$t=\frac{\bar x-\mu}{s/\sqrt{n}}$

$=\frac{43350-48500}{15000/\sqrt{50}}\\\\=-2.42773\\\\\approx -2.43$

Thus, the test statistic value is -2.43.

Compute the p-value of the test as follows:

$p-value=2\times P(t_{49}>-2.43)=0.0188$

*Use a t-table.

Thus, the p-value of the test is 0.0188.

Decision rule:

If the p-value of the test is less than the significance level then the null hypothesis will be rejected and vice-versa.

p-value = 0.0188 > α = 0.01

The null hypothesis will not be rejected at 1% level of significance.

Thus, concluding that there is not enough evidence to suggest that mean starting salary of a graduate with a bachelor in economics is different from $48,500.

for a fixed voltage, the current in an electrical circuit varies inversely as the resistance in the circuit. If a certain has a

Tatiana [17]

Answer: 1.75 amps

Step-by-step explanation:

V (voltage) = I (current) · R (resistance)

V = 3.5 (110)

= 385

When Resistance is doubled, the current is cut in half.

V = I R

385 = I (2 · 110)

$\dfrac{385}{220}=\text{I}$

1.75 = I

After the price of petroleum oil went up by 10%, a consumer reduced his oil consumption by the same percent. By what percent wou

IgorLugansk [536]

Let's assign some random values to it, and say 1 unit of petroleum costs 100 bitcoins, because we all know bitcoins are the best currency :P

If the price goes up by 10%, it is now 100*1.1 = 110bitcoins for 1 unit.

However he's only getting 0.9 units now, so multiplying 110 by 0.9 gives us 99 bitcoins. His petroleum bill used to be 100 (which is why I picked 100 as it's easier), and now it is 99. Therefore his petroleum bill has reduced by 1%
