Answer:
a. Fail to reject the null hypothesis.
Step-by-step explanation:
Here we test the claim that proportion of reachers is really 41%
![H_0: p =0.41\\H_a: p \neq 0.41](https://tex.z-dn.net/?f=H_0%3A%20p%20%3D0.41%5C%5CH_a%3A%20p%20%5Cneq%200.41)
(Two tailed test at 1% significance level)
Observed proportion = 0.36
Sample size n = 100
Std error of proportion = ![\sqrt{\frac{pq}{n} } \\=\sqrt{\frac{0.41*0.59}{100} } \\=0.0492](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7Bpq%7D%7Bn%7D%20%7D%20%5C%5C%3D%5Csqrt%7B%5Cfrac%7B0.41%2A0.59%7D%7B100%7D%20%7D%20%5C%5C%3D0.0492)
p difference = 0.36-0.41 =- 0.05
Test statistic Z = p diff/std error =-1.0166
p value=0.286
Since p >0.01 we accept null hypothesis.
a. Fail to reject the null hypothesis.
Answer:
146
Step-by-step explanation:
angle AB is an inscribed angle and arc AB is it's intercepted arc
An inscribed angle is equal to half the measure of its intercepted arc
Which means that an intercepted arc is equal to two times the measure of its corresponding inscribed angle
Thus, arc ab = 2(73)
2 * 73 = 146
hence, arc AB = 146
Answer:
Step-by-step explanation:
axiom goes with a given definition assumed to be true
theorem goes with a logical argument showing that a theorem is true
proof is a statement that requires proof
Answer:
x=11
Step-by-step explanation:
2[x+7]=36
you take 2 times x and 2 times 7
2x+14 =36
-14 -14
2x = 22
you take 2x divided by you and you have x
22 divided by 2 you have 11.
