Answer: it’s (3,2)
Step-by-step explanation:
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
![H_0: \bar x = \bar y\\H_a: \bar x \neq \bar y](https://tex.z-dn.net/?f=H_0%3A%20%5Cbar%20x%20%3D%20%5Cbar%20y%5C%5CH_a%3A%20%5Cbar%20x%20%5Cneq%20%5Cbar%20y)
(two tailed test)
Std error for difference = 4.342
Test statistic t = ![\frac{0.45}{4.342} \\=0.1036](https://tex.z-dn.net/?f=%5Cfrac%7B0.45%7D%7B4.342%7D%20%5C%5C%3D0.1036)
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
Answer:
150161 in base 8.
= 347^2 base 8.
Step-by-step explanation:
11100111^2
the last 4 digits of this binary number = 7 in base 10.
The number 11100000 in base 10 = 1*2^5 + 1*2^6 + 1*2^7
= 224 base 10
So 11100111 = 231 base 10.
231^2 = 53361.
Now convert this to base 8:
We divide by 8
8 | 53361
8 | 6670 remainder 1
8 | 833 rem 6
8 | 104 rem 1
8 | 13 rem 0
8 | 1 rem 5
| 0 rem 1
So the answer is 150161
Answer:
Table A
Step-by-step explanation:
y = 3x^2 +2x -8
The quadratic is in the form
y = a x^2 +bx+c
a = 3 b = 2 c = -8
Since a > 0 it opens up
The y intercept is c so the y intercept is -8
