Answer:
70
Step-by-step explanation:
70 combinations of four books can be made from eight different books.
Tomorrow night at ten because 48 hours is two days. So two days from last night at ten.
2x+10x combine like terms
12x
2(x-4)+4 Distribute 2
2x-8+4
combine like terms
2x-4
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
