Answer: Choice 2) sin(B) = cos(90-B)</h3>
Explanation:
The rule is that
sin(A) = cos(B)
if and only if A+B = 90.
Solving for A gets A = 90-B
So we end up with
sin(90-B) = cos(B)
which is the same as
cos(B) = sin(90-B)
SOLUTION:
Case: Hypothesis testing
Step 1: Null and Alternative hypotheses

Step 2: T-test analysis

Step 3: t-test with the significance level

Step 4: Comparing

So tail to reject the null hypothesis. There is enough evidence at a 0.05 level of significance to claim that the mean spent is greater than P127.50.
Final answer:
Yes, there is evidence sufficient to conclude that the mean amount spent is greater than P127.50 per month at a 0.05 level of significance.

Answer:
72
Step-by-step explanation:
h(4) = 4^3 -2·4 = 64 -8 = 56
g(4) = 3·4 +4 = 16
Then the sum is ...
(h+g)(4) = h(4) + g(4) = 56 +16
(h+g)(4) = 72
Answer:
a) In the explanation.
b) P=0.09714
c) P=0.0866
d) p=0.208
Step-by-step explanation:
a) The sampling distribution will have this properties:
1 - The sampling distribution of a proportion is equal to the binomial distribution.
2 - The mean of the sampling distribution will be equal to the proportion of the population (0.328).

3 - The standard deviation will be equal to the square root of the product of the proportion and its complementary, divided by the sample size.

B) The fraction with sample proportion of 0.45 or higher is

C) The fraction with sample proportion of 0.20 or lower is

D) The value of p that cuts off the lower 10% of the distribution corresponds to z=-1.28.
Then we have
