If 1 gram = 100 centigrams and 1 centigram = 10 milligrams, how many
Alja [10]

Answer:

1,420 milligrams

Step-by-step explanation:

We know there are 100 centigrams in 1 gram, and there are 10 milligrams in a centigrams. That would mean there are 1,000 milligrams in 1 gram (100 * 10 = 1000).

As a result, all you need to do is multiply 1.42 by 1000 to get the amount of milligrams.

1.42 * 1000

Alternatively, to make 1.42 a whole number first, multiply by 100, then add a zero. (That's the other 10!)

(1.42 * 100) * 10

142 * 10

There are 1,420 milligrams in 1.42 grams.

​Goodness-of-fit hypothesis tests are always​ ________.
oksian1 [2.3K]

Answer:

Right tailed tests

Step-by-step explanation:

When dealing with the chi-square goodness-of-fit test, we are trying to find out if the sample in question comes from the population with the claimed distribution.

Now, the idea behind this concept is that if the observed value is very close to the expected/claimed value, it means the square of the deviations will now be small. The weighted square deviations will now be calculated and if their sum is small, it means the observed values will be close to the expected values and there would thus be no reason to reject the claim that it came from the distribution. Thus, it's only when the sum is large, that there would be a reason for questioning the distribution.

Thus, goodness of fit tests are always right tailed tests.
