Answer:
D. 113
Step-by-step explanation:
If you take the other numbers and subtract each from the original 236, they all exceed the amount. So the answer would be 113.
Answer:
There is evidence for the claim that less than 10% of the test results are wrong
Step-by-step explanation:
Given that the company Drug Test Success provides a "1-Panel-THC" test for marihuana usage.
Among 300 tested subjects, results from 27 subjects were wrong (either a false positive or a false negative.)
Sample proportion = ![\frac{27}{300} \\=0.09](https://tex.z-dn.net/?f=%5Cfrac%7B27%7D%7B300%7D%20%5C%5C%3D0.09)
H0: p = 0.10
Ha: p <0.10
(left tailed test)
p difference = 0.09-0.10 = -0.01
Std error = ![\sqrt{0.1*0.9/300} \\=0.005196](https://tex.z-dn.net/?f=%5Csqrt%7B0.1%2A0.9%2F300%7D%20%5C%5C%3D0.005196)
z statistic = -1.9245
p value = 0.027
Since p <0.05 we reject H0
There is evidence for the claim that less than 10% of the test results are wrong
If your looking for for x it would be X = 4
