the correct answer is c 78
Step-by-step explanation:
lit can't be a because to small and can't be b because also to small. and and 92 is uptus and this is an acute angle
Check if you can write an equation relating the term number to the actual value
n1=3
n2=10 = 3+7
n3= 17 = n2+7 = n1+7+7 = n1 +2*7
n4= 24 = n1+3*7
so you will notice a pattern
for the x-th term
n_x =3+(x-1)*7
the 50th term would be n_50 = 3+(50-1) * 7
Answer:
The value of the test statistic is ![t = 1.97](https://tex.z-dn.net/?f=t%20%3D%201.97)
Step-by-step explanation:
The null hypothesis is:
![H_{0} = 250](https://tex.z-dn.net/?f=H_%7B0%7D%20%3D%20250)
The alternate hypotesis is:
![H_{1} \neq 250](https://tex.z-dn.net/?f=H_%7B1%7D%20%5Cneq%20250)
Our test statistic is:
![t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D)
In which X is the sample mean,
is the null hypothesis value,
is the standard deviation and n is the size of the sample.
In this problem:
![X = 251.6, \mu = 250, \sigma = 5.4, n = 44](https://tex.z-dn.net/?f=X%20%3D%20251.6%2C%20%5Cmu%20%3D%20250%2C%20%5Csigma%20%3D%205.4%2C%20n%20%3D%2044)
So
![t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7BX%20-%20%5Cmu%7D%7B%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D)
![t = \frac{251.6 - 250}{\frac{5.4}{\sqrt{44}}}](https://tex.z-dn.net/?f=t%20%3D%20%5Cfrac%7B251.6%20-%20250%7D%7B%5Cfrac%7B5.4%7D%7B%5Csqrt%7B44%7D%7D%7D)
![t = 1.97](https://tex.z-dn.net/?f=t%20%3D%201.97)
The value of the test statistic is ![t = 1.97](https://tex.z-dn.net/?f=t%20%3D%201.97)
