Answer: No, these results are not statistically significant because
p > 0.05
Step-by-step explanation:
The null hypothesis is
H0 : μ = 17
The alternative hypothesis is
H 1 : μ ≠ 17
where μ is the mean amount of cereal in each box.
The p value that he got is 0.1499. This is greater than alpha = 0.05 which is the given level of significance.
If the level of significance is lesser than the p value, we would accept the null hypothesis.
Therefore, the correct option is
No, these results are not statistically significant because p>0.05
Answer: The slope is 5
Step-by-step explanation:
You can calculate the slope of the line with this fomula:
Given the points (2,3) and (1,-2), you can identify that:
Now, the final step is to substitute these values into the formula , getting that the slope of this line is:
First substitute
(3)(4)/4
then simplify.
12/4
then solve
3

Answer:
Step-by-step explanation:
Given the right triangle in the image, you need to remember the following identity:
Observe the triangle. You can identify that:
Then, knowing these values, you can substitute them into :
Finally, you have to solve for "x".
Therefore, the value of "x" rounded to the nearest tenth is:
