Answer:
The null and alternative hypotheses are:


Under the null hypothesis, the test statistic is:

Where:
is the sample mean
is the sample standard deviation
is the sample size


Now, we can find the right tailed t critical value at 0.01 significance level for df = n-1 = 10 - 1 = 9 using the t distribution table. The t critical value is given below:
Since the test statistic is less than the t critical value, we therefore, fail to reject the null hypothesis and conclude that there is not sufficient evidence to support the claim that the people do better with the new edition.
Answer:
Step-by-step explanation:
Turn the question around so it is easier to see.The open end is closest to n.
6n>48 Divide by 6
6n/6>48/6
n > 8
So all you have to do is choose 3 values greater than 8
How about 9,10,11
Answer: -3a - 8
Step-by-step explanation:
(13 a - 5 ) - (16a + 3) = 13 a - 5 - 16a - 3 = -3a -8
Answer: 8.78
Step-by-step explanation:
Because both potatoes and carrots can be classified as vegetables, this problem is simple addition of 7.95 and 0.83, or 8.78.
Hope it helps :)
Divide both sides of -105=-5g by -5. You'll get g = -105 / (-5), or g = 21.
