Answer:
129
Step-by-step explanation:
278 - 149 = 129
Answer:
P-value is lesser in the case when n = 500.
Step-by-step explanation:
The formula for z-test statistic can be written as

here, μ = mean
σ= standard deviation, n= sample size, x= variable.
From the relation we can clearly observe that n is directly proportional to test statistic. Thus, as the value of n increases the corresponding test statistic value also increases.
We can also observe that as the test statistic's numerical value increases it is more likely to go into rejection region or in other words its P-value decreases.
Now, for first case when our n is 50 we will have a relatively low chance of accurately representing the population compared to the case when n= 500. Therefore, the P-value will be lesser in the case when n = 500.
3x +0 can be replaced by 3x because of "the additive identity property of real numbers: anything plus zero is that thing."
The simplest ratio is 1/3. Equivalent ratios would be 3/9 and 5/15.
The next larger hundred is 100 .
The next smaller hundred is zero.
36 is closer to zero than it is to 100 .
So the nearest hundred to 36 is zero.
