Answer:
68
Step-by-step explanation:
derive that 25 percent of 68 equals 17.
Answer:
45%
Step-by-step explanation:
To find the percentage decrease, we need to find the decrease first.
Decrease = 812 - 446.6
= 365.4
Percentage decrease = × 100%
= 45%
Well 4/5 is 80% and 9/10 is 90%
9/10 is bigger. :)
Answer:
x = 18
Step-by-step explanation:
the inequality is 9 1/2x.
if x = 18, the inequality is true.
9 1/2(18)

<h3>What is statistical inference?</h3>
statistical inference uses sample data to make estimates of or draw conclusions about one or more characteristics of a population.
The purpose of statistical inference is to estimate this sample to sample variation or uncertainty. Understanding how much our results may differ if we did the study again, or how uncertain our findings are, allows us to take this uncertainty into account when drawing conclusions. It allows us to provide a plausible range of values for the true value of something in the population, such as the mean, or size of an effect, and it allows us to make statements about whether our study provides evidence to reject a hypothesis.
We have four ideas for using the statistical inference.
1. Estimating uncertainty.
2. Confidence intervals.
3. Hypothesis tests.
4. Connections with other material.
