Answer:
The scientist’s conclusion is not appropriate because it is based on a subjective appreciation (“significantly greater than”).
<em>How “greater” is “significantly greater”?
</em>
A more objective and technical approach would be fixing a level of significance, let's say 0.05 or 0.01 for example, measuring the samples means and standard deviations and then proceeding with an appropriate hypothesis testing in order to see if the differences in means are really significant.

Answer:
4 is the square root of 2 and it's less than 9
Answer:
10/13 ≤ x < 18/13
Step-by-step explanation:
-1 ≤ 13x - 11 < 7
If a ≤ u < b then a ≤ u and u < b
⇒ -1 ≤ 13x - 11 and 13x - 11 < 7
-1 ≤ 13x - 11
Add 11 to both sides: 10 ≤ 13x
Divide both sides by 13: 10/13 ≤ x
13x - 11 < 7
Add 11 to both sides: 13x < 18
Divide both sides by 13: x < 18/13
Combine the intervals
10/13 ≤ x < 18/13
