Ones: 853
Answer:
16
Step-by-step explanation:
range= highest value - lowest value
Hi
1. Temp was 5 at noon and dropped 59 degrees at midnight. 5+(-59)= -54 (B)
2. The stock dropped by 5 points and opened at 93 points that day.
93+(-5)=88 points (B)
3. The temperature fell by 12° over 4 hours.
12÷4=3° decreased per hour (C)
Hope that clarifies these. Let me know if these aren't clear.
We are given the data on the number of candies handed by neighborhood A and neighborhood B.
Let us first find the mean and variance of each neighborhood.
Mean:


Variance:


A. Null hypothesis:
The null hypothesis is that there is no difference in the mean number of candies handed out by neighborhoods A and B.

Research hypothesis:
The research hypothesis is that the mean number of candies handed out by neighborhood A is more than neighborhood B.

Test statistic (t):
The test statistic of a two-sample t-test is given by

Where sp is the pooled standard deviation given by


So, the test statistic is -1.74
Critical t:
Degree of freedom = N1 + N2 - 2 = 6+6-2 = 10
Level of significance = 0.05
The right-tailed critical value for α = 0.05 and df = 10 is found to be 1.81
Critical t = 1.81
We will reject the null hypothesis because the calculated t-value is less than the critical value.
Interpretation:
This means that we do not have enough evidence to conclude that neighborhood A gives out more candies than neighborhood B.
27-1= 26 (the one book beside her bed)
26/8= 3.25, but there isn’t .25 of a shelf, so she needs 4 shelves to fit all of her books
