(a) H0:μ1=μ2; Ha:μ1≠μ2, which is a two-tailed test.

Step-by-step explanation:

We formulate the

H0: μ1=μ2; null hypothesis that the two means are equal and alternate hypothesis that the two mean are not equal.

Ha:μ1≠μ2 Two tailed test

Test statistic used is

t= x1`-x2` / s√n as the variances are equal and sample size is same

T value for 9 degrees of freedom for two tailed test at α = 0.05 is 2.26

P- value for t test for 9 degrees of freedom is 0.125 from the table.

Hence only a is correct .

The sum of two consecutive even numbers is 210.
WITCHER [35]

Answer:

104, 106

Step-by-step explanation:

Hello!

A consecutive number is a number that comes after the other.

Let the first even integer be x. Since there is an even integer for every two integers, the second number should be x + 2.

<h3>Solve for x</h3>
  • (x) + (x + 2) = 210
  • x + x + 2 = 210
  • 2x + 2 = 210
  • 2x = 208
  • x = 104

The second number is x + 2, so it would be 106.
