Total charge
[(30×1.5)+(10.5×1.5)]+100%=60.75
100%=60.27
So total charge is
(30×1.5)+(10.5×1.5)+100%=121.50
There are only 9 single digit numbers from 1-50: (1, 2, 3, 4, 5, 6, 7, 8, 9)
To find the percent, we divide 9 by 50
9/50=0.18
Now, we multiply our answer by 100
0.18(100)=18%
There’s an 18% chance of pulling a single digit number out of a jar with numbers from 1 to 50
Answer:
c. There is insufficient evidence to conclude that there is a significant difference between the means of the statistics day students and night students on Exam 2
Step-by-step explanation:
Given that a statistics instructor believes that there is no significant difference between the mean class scores of statistics day students on Exam 2 and statistics night students on Exam 2.
Group Group One Group Two
Mean 75.8600 75.4100
SD 16.9100 19.7300
SEM 2.8583 3.2436
N 35 37
*SEM is std error/sqrt n
Mean difference = 0.4500
(two tailed test)
Std error for difference = 4.342
Test statistic t =
df =70
p value = 0.9178
Since p >0.05 we accept H0
c. There is insufficient evidence to conclude that there is a significant difference between the means of the statistics day students and night students on Exam 2
