Answer:
Check the explanation
Step-by-step explanation:
Hypotheses are:
![H_{0}:\mu_{1}=\mu_{2},H_{1}:\mu_{1}\neq \mu_{2}](https://tex.z-dn.net/?f=H_%7B0%7D%3A%5Cmu_%7B1%7D%3D%5Cmu_%7B2%7D%2CH_%7B1%7D%3A%5Cmu_%7B1%7D%5Cneq%20%5Cmu_%7B2%7D)
Following is the output of t test:
Hypothesis Test: Independent Groups (t-test, pooled variance)
X1 X2
12 15.5 mean
3.6591 3.6839 std. dev.
10 15 n
23 df
-3.5000 difference (X1 - X2)
13.4999 pooled variance
3.6742 pooled std. dev.
1.5000 standard error of difference
0 hypothesized difference
-2.33 t
.0287 p-value (two-tailed)
The p-value is:
p-value = 0.0287
Since p-value is less than 0.05 so we reject the null hypothesis. That is we can conclude that the exercise program have a significant effect.
(b)
The cohen's d is
![d=\left |\frac{\bar{x}_{1}-\bar{x}_{2}}{s_{p}} \right |=\left |\frac{12-15.5}{3.6742 } \right |=0.95](https://tex.z-dn.net/?f=d%3D%5Cleft%20%7C%5Cfrac%7B%5Cbar%7Bx%7D_%7B1%7D-%5Cbar%7Bx%7D_%7B2%7D%7D%7Bs_%7Bp%7D%7D%20%5Cright%20%7C%3D%5Cleft%20%7C%5Cfrac%7B12-15.5%7D%7B3.6742%20%7D%20%5Cright%20%7C%3D0.95)

Step-by-step explanation:
comment what i could do for u.
You need to find the GCF of both numbers. Both of these numbers have a GCF of 1 so the answer is already in simplest form. Unless you want it in a decimal which in that case you just divide. 5.34

Step-by-step explanation:
Answer:
1/2 cups of apple juice.
Step-by-step explanation:
The ratio between apple juice to carrot juice is
1/4 : 1/2
By using this ratio we can find the number of cups of apple juice needed for one cup of carrot juice.
since 1 cup is twice the carrot juice in the ratio, we need twice the ratio in the apple juice as well.
1/4 * 2 = 2/4
This can be simplified to 1/2
