10.

If we find that the difference between the sample mean is a rare event, we will conclude that:

the null hypothesis is accepted.
the alternative hypothesis is rejected.
the null hypothesis is rejected.
there is no difference between the populations.

Answer #1

A null hypothesis is a hypothesis that says there is no statistical significance between the two variables

An alternative hypothesis is one that states there is a statistically significant relationship between two variables

If a highly unlikely event occurs, then we explain this by stating that a rare event really did take place, or that the assumption we started with was not true.

Thus, we conclude that

the null hypothesis is rejected (alternative hypothesis is accpeted)

For a random sample of 10 light bulbs, the mean bulb life is 4,000 hr with a sample standard deviation 200. For another brand of bulbs, a random sample of 8 has a sample mean of 4,300 hr and a sample standard deviation of 250. Assume that the life of a light bulb is normally distributed and the standard deviations of the two populations are equal. We test the hypothesis that there is no difference between the mean operating life...

An urn contains 10 marbles, of which M are white and 10 −M are black. To test that M = 5 against the alternative hypothesis that M = 6, one draws 3 marbles from the urn without replacement. The null hypothesis is rejected if the sample contains 2 or 3 white marbles; otherwise it is accepted. Find the size of the test and its power.
