Answer:

The correct option is c which is if this test was one-tailed instead of two-tailed, you would reject the null.

Step-by-step explanation:

a: This statement cannot be true as the p-value for a 1 tailed test is dependent on the level of significance and other features.

b: This statement cannot be true as there is no valid mathematical correlation between the p-value of the one-tailed test and the current p-value.

c: This statement is true because due to the enhanced level of significance, the null hypothesis will not be rejected.

d: This statement is inverse of statement c which cannot be true.

e: The statement cannot be true as there is no correlation between the current p-value and the p-value of 1 tailed test. The correlation exists between the values of one-tailed and two-tailed p-values.

A bookmark is shaped like a rectangle with a semicircle attached at both ends. The rectangle is 17 cm

maria [59]

Answer:

80.56

Step-by-step explanation:

To find the rectangle area you just multiply its length by its width:

17 * 4 = 68

You have to sum two semicircles on top of that. Since it is 2 semicircles you can just calculate one circle. Using the circle area formula: $\pi*r^2$

Since the radius (r) is 2 and $\pi$ is 3.14, you have the following equation:

A = 3.14 * 2² ==> A = 3.14 * 4 ==> A = 12.56 <em>(A is Area)</em>

Sum the rectangle's area with the circle's area:

12.56 + 68 = 80.56

And vuoila! there's your answer.

What is the LCD of 1/6 and 5/12 and 11/18

Oksi-84 [34.3K]

Finding the Lowest Common Denominator of: $\frac{1}{6} ; \frac{5}{12} ; \frac{11}{18} 
$

Here's to find out how it was our LCD: $\frac{1}{6} = \frac{6}{36}$
$\frac{5}{12} = \frac{15}{36}$
$\frac{11}{16} = \frac{22}{36}$
To find the fraction on the right side we had to multiply (and somewhat divide to get the answer)

So, therefore the Lowest Common Denominator of this question would most likely be: $36$

Good Luck!
