g If a hypothesis test with a significance level of α rejects H0: μ1=μ2 in favor of Ha: μ1≠μ2, then thecorresponding (1- α)% con
Effectus [21]

Answer:

The statement, (1- <em>α</em>)% confidence interval for (μ₁ - μ₂) does not contain zero is TRUE.

Step-by-step explanation:

The hypothesis for a test is defined as follows:

<em>H</em>₀: μ₁ = μ₂ vs. <em>H</em>ₐ: μ₁ ≠ μ₂

It is provided that the test was rejected st the significance level <em>α</em>%.

If a decision is to made using the confidence interval the conditions are:

If the null hypothesis value is not included in the (1 - <em>α</em>)% confidence interval then the null hypothesis will be rejected and vice versa.

In this case the null hypothesis value is:

<em>H</em>₀: μ₁ - μ₂ = 0.

If the value 0 is not included in the (1 - <em>α</em>)% confidence interval for the difference between two means, then the null hypothesis will be rejected.

Thus the statement, (1- <em>α</em>)% confidence interval for (μ1- μ2) does not contain zero is TRUE.

13. Solve 2/3 + 5/6 and put answer in simplest<br> form.<br> O A. 11/2<br> B.<br> c. 76<br> D.776
Tamiku [17]

Answer:

3/2 or 1 + 1/2

i havent done fractions in a long time but this is what i got from memory

you turn the 2/3 into 4/6 so they can easily be added together to get 9/6 which can be simplified to 3/2 or in proper form 1 + 1/2

You invest $2,000 in an account that is compounded annually at an interest rate of 5%. You never withdraw money from the account
Yuki888 [10]
Formula for amount for compound interest:

Amount, A =  P(1 + r/100)^n

Where r is rate, P is principal, and n is the number of years.

P = 2000, r = 5, n = t years.

A = 2000( 1 + 5/100)^t

A = 200(1+0.05)^t

A = 2000(1.05)^t

A(t) = 2000(1.05)^t

None in the option look like the answer we have.

Except you didn't type the last option correctly.

According to a state law for vehicles traveling on state roads, the maximum total weight of a vehicle and its contents depends o
Alex787 [66]

Inequalities are used to show the relationship between unequal expressions.

The inequalities that represent the maximum weights are:

  • <em>2 axles - </em>x \le 40000<em>.</em>
  • <em>3 axles - </em>x \le 60000<em>.</em>
  • <em>4 axles - </em>x \le 80000<em>.</em>

<em />

Let the maximum weight be represented with x

In inequality, maximum means less than or equal to i.e. \le

<u>(a) 2 axles</u>

The maximum weight, here is 40000.

So, the inequality is:

x \le 40000

<u>(b) 3 axles</u>

The maximum weight, here is 60000.

So, the inequality is:

x \le 60000

<u>(c) 4 axles</u>

The maximum weight, here is 80000.

So, the inequality is:

x \le 80000

<em>See attachment for the graphs of each inequality</em>
