Suppose that competing hypotheses for a test are H0: p1 - p2 = 0 versus HA: p1 - p2 ≠ 0. A 95% confidence interval for the diffe

rence between the population proportions is calculated as [0.25, 0.40]. At the 5% significance level, the correct conclusion to the hypothesis test is

Answer:

Step-by-step explanation:

Given that in a hypothesis test for comparison of two proportions p1 and p2

two tailed at 95% confidence level

the confidence interval was (0.25,0.40)

The hypothesis was for

H0: p1 - p2 = 0 versus HA: p1 - p2 ≠ 0

As per null hypothesis the difference between proportions should be 0.

In our confidence interval we find lower limit is 0.25 and upper limit is 0.40

i.e. 0 is not contained in this interval and 0 is significantly far from this 0.25 even lower limit

So we can conclude that the difference between proportions cannot be 0 but is positive

So reject null hypothesis.

There is significant difference between proportions at 95% confidence level

A tank weighs 5.6kg when it 1/4 filled with water.If it weighs 10.4kg when it is full ,what will be it's weight when it is empty
Schach [20]

Answer:

4 kg

Step-by-step explanation:

so 1.6 * 4 is 6.4 so you just double check if you want

4 + 1.6 which is 1/4 of 6.4 will be 5.6 (matches with the question)

4 + (1.6*4) (indicates it's full) = 10.4( also Matches with the question)

there is another way by setting up an equation. let me know in comments if you want to see it that way

Which statements are true from the graph ? Check all that apply:
Flura [38]

The statements that are true from the graph are:

  • The line is horizontal
  • The line goes through (4, 4 )
  • The y- values are all 4

<h3>Calculations and Parameters</h3>

Given the graph, we can note some things:

  • There is a line with a slope of zero.
  • This is a horizontal line parallel to the x-axis.
  • The equation of the line is y = c

c is the value of the y- coordinates the line passes through.

The line passes through (0, 4 ) with a y- coordinate of 4

Therefore, the equation of the line of y= 4
