Answer:
(b) 0.251
Step-by-step explanation:
1. Standard deviation equation:
Where X is the mean of the data, and N the amount of data. Then, N=5
2. Estimate the Mean:
3. Caclulate Standard deviation:
Answer:
Step-by-step explanation:
The claim being tested is that p not equals ≠ 0.877
A) This is the alternative hypothesis and it is a two tailed test. It means that it can be in either direction.
B)Given that z = 2.94, the p value would be determined from the normal distribution table. Since the curve is symmetrical and it is a two tailed test, the p for the left tail and the right tail would be considered. We will look at the area in both tails. Since it is showing in one tail only, we would double the area
From the normal distribution table, the area above the test z score in the right tail is 1 - 0.998 = 0.002
We would double this area to include the area in the left tail of z = - 2.94 Thus
p = 0.002 × 2 = 0.004
C) Since alpha, 0.01 > than the p value, 0.004, then we would reject the null hypothesis, H0
Answer:
Option A
Step-by-step explanation:
Option A because there is two completely different events going on, and they have nothing to do with each other.
