Question

WHAT IS IT
ACTIVITY 1
A. Read and understand the given statements below and find out whether it is
a null hypothesis. In your notebook, write H, if the given is a null hypothesis.
Otherwise, just leave it blank.
In 2015, it was recorded that around 34% of the population in 2015 were not
narried. A researcher surveyed a random sample of 500 couples. He found out that
8% of them were living together but unmarried. Test at 5% significance level if the
urrent percentage of unmarried couples is different from 34%.
The current percentage of unmarried couples is different from 34%.
The current percentage of unmarried couples is 34%.​

Answer 1

Null hypothesis formula

Step-by-step explanation:

The null hypothesis always has the form H0:μ=μ0 for a specific number μ0 (in the respirator example μ0=75, in the textbook example μ0=127.50, and in the baked goods example μ0=8.0).

Answer 2

Answer:

In reviewing hypothesis tests, we start first with the general idea. Then, we keep returning to the basic procedures of hypothesis testing, each time adding a little more detail.

The general idea of hypothesis testing involves:

Making an initial assumption.

Collecting evidence (data).

Based on the available evidence (data), deciding whether to reject or not reject the initial assumption.
