Answer:
The Number is 8.
Step-by-step explanation:
Let the number be x.
Given:
1/2 is subtracted from four times the reciprocal of a number, the result is 0.
Hence the equation will become like;

Now Solving the equation we get.

Now the we can see the number is 8, when 1/2 is subtracted from 4 times the reciprocal of number means 4/8 which becomes 1/2 and hence when 1/2 is subtracted from 1/2 it equals to 0.
Hence the number is 8.
Answer:1 1/15
Step-by-step explanation:2 2/3 minus 1 9/15 is 1 /15 because I said so.
According to the null hypothesis, the test statistic of the proportion is of z = 120.1.
<h3>
What is the null hypothesis?</h3>
The claim is that the rate of nausea is greater than the 6% rate experienced by flu patients given a placebo. At the null hypothesis, we consider the claim as false, hence the null hypothesis is:

<h3>What is the test statistic?</h3>
The test statistic is given by:

In which:
is the sample proportion.
- p is the proportion tested at the null hypothesis.
In this problem, the parameters are:

Hence, the test statistic is given by:
