Answer:
$244.25
Step-by-step explanation:
First, the question is asking what the change in her savings account balance is each month. So, you know that you are looking for the amount that is lost each month. When it says that at the end of the year, she has payed $2,931 , what is implied is that she has spent that much over 12 months. So all that is needed to do is divide her balance change over the year by 12 to find the monthly balance change.
Answer:
Step-by-step explanation:
Males proportion ![p_1 = \frac{163}{532} =0.3064](https://tex.z-dn.net/?f=p_1%20%3D%20%5Cfrac%7B163%7D%7B532%7D%20%3D0.3064)
Females proportion ![p_2 = \frac{203}{589} =0.3447](https://tex.z-dn.net/?f=p_2%20%3D%20%5Cfrac%7B203%7D%7B589%7D%20%3D0.3447)
![H_0: p_1 = p_2\\H_a: p_1](https://tex.z-dn.net/?f=H_0%3A%20p_1%20%3D%20p_2%5C%5CH_a%3A%20p_1%20%3Cp_2)
(one tailed test for comparison of proportions)
Test statistic = ![\frac{p_1-p_2}{p(1-p)\sqrt{\frac{1}{n_1}+\frac{1}{n_2} } }](https://tex.z-dn.net/?f=%5Cfrac%7Bp_1-p_2%7D%7Bp%281-p%29%5Csqrt%7B%5Cfrac%7B1%7D%7Bn_1%7D%2B%5Cfrac%7B1%7D%7Bn_2%7D%20%20%7D%20%7D)
=-1.3641
Here p= combined proportion = ![\frac{163+203}{532+589} \\=0.3291](https://tex.z-dn.net/?f=%5Cfrac%7B163%2B203%7D%7B532%2B589%7D%20%5C%5C%3D0.3291)
p value = 0.0869
Since p >0.05, accept null hypothesis.
The evidence does not suggest a higher proportion of females are annoyed by this behavior
Answer:
degree 0.089
radian -0.92
