Answer:
The statistical conclusion is:
a) Your results are significant; one's willingness to wear masks is not independent of one's age.
Step-by-step explanation:
From this experiment,
The null hypothesis is established as:
H 0 = one's willingness to wear masks is independent of one's age.
The alternate hypothesis is established as:
H 1 = one's willingness to wear masks is not independent of one's age.
In statistics, if the absolute value of the test statistic is greater than the critical value, we declare statistical significance and reject the null hypothesis.
Since the test statistic = 16.5, which is higher than the critical value of 7.82, this establishes statistical significance. Thus, the null hypothesis is rejected.
Therefore, the statistical conclusion is that one's willingness to wear masks is not independent of one's age.
You find a common denominator, for example, if you want to subtract 3/4 minus 1/2 you would have to multiply 1/2 by 2/2, which equals 2/4, then you can do 3/4-2/4, which is 1/4. Sorry if it’s a bit confusing, hope it helps!
Answer:
13
Step-by-step explanation:
If x is 7, then 7 * 2 = 13, and 14 - 1 = 13.

Answer:
197%
Step-by-step explanation:
1.97 = 437/860.89
1.97=197%
180-108= 172 172 divided by 5 is 14.4 z=14.4
180-67=113 y=113
