Answer:
The probability that a person will get 17 or more right, if the person is truly guessing, is about 12.9%.
The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.
Step-by-step explanation:
The system of hypothesis fo this case are:
Null hypothesis:
Alternative hypothesis:
That's a upper right tailed test.
The p-value is the probability of obtaining the observed results of a test, assuming that the null hypothesis is correct.
And this value allows to reject or not the null hypothesis.
If we reject the null hypotheis at the significance level. That indicates strong evidence against the null hypothesis, so you reject the null hypothesis.
If then we say that we fail to reject the null hypothesis at the significance level. That indicates weak evidence against the null hypothesis, so you fail to reject the null hypothesis.
Answer:
C. 10

8*4 is 32
32/2 is 16
20-16 is 4
4+6 IS 10
Answer:
2x5x5
Step-by-step explanation:
Exponential Form: 2^1 x 5^2
The rate of 28,000% per month is extremely big. I believe
the correct monthly rate is 2.8% (correct me if I am wrong though). Next time
kindly check the given values.
Rate is expressed in a factor of:
(1 + r)^n
where r is the rate and n is the number of months
First we calculate for the rate in a year (1 year = 12
months). We know that the rate must be constant, therefore:
rate in a month = rate in a year
(1 + 0.028)^1 = (1 + r)^(1/12)
r = 0.3929
Therefore there is an increase of about 39.29% in a year.
Then we calculate for the rate in a day (1 month = 30
days). The rate must also be constant, therefore:
rate in a month = rate in a day
(1 + 0.028)^1 = (1 + r)^(30)
r = 9.21 * 10^-4
Therefore there is an increase of about 0.092% per day.
