Answer:
-17
Step-by-step explanation:
Substituting c=-3
4*-3-5
=-12-5
=-17
Answer:
(B) Because the confidence interval includes 0, we don't have convincing evidence that sugar causes faster reading times, on average.
Step-by-step explanation:
Confidence Interval for the population mean difference in reading is basically an interval of range of values where the true population mean difference in reading time can be found with a certain level of confidence.
Mathematically,
Confidence Interval = (Sample mean) ± (Margin of error)
In using confidence interval of population mean difference in reading times for hypothesis testing, if the interval obtained contains a value of 0, it means the population mean difference in reading times can take on a value of 0 and indicate that there isn't enough evidence to conclude that there is a significant difference in the two quantities being compared. (The null hypothesis is true).
If the interval doesn't contain a 0, then it can be concluded that there is enough evidence to conclude that there is significant difference in the two quantities being compared.
Hope this Helps!!!
Answer:
Yes
Step-by-step explanation:
3:2 = 5 people
3:1 = 4 people
5+4=9 people
The equation would be 35.75x+6y=190
Remove ( ), factor, least common multi of, adjust, expand, answers is : X^2-15x+6 / (x+3)(x-3)
