Answer:
The alternate hypothesis is:
Step-by-step explanation:
There are two types of hypothesis. The null hypothesis and the alternate hypothesis. The null hypothesis is that the mean found is equal to the expected value. The alternate hypothesis is a question about this expected value(different, more, less)
A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore.
This means that the null hypothesis is
Let us say that we want to set up a statistical test to see if the wave action (i.e., height) is dying down. If you wanted to test the hypothesis that the waves are dying down, what would you use for the alternate hypothesis
Dying down means lower average peak, that is, lower than the average of 16.4. This means that the alternate hypothesis is:
Answer:
It is impossible that the mean of the sample of 100 fertilizers less than 2 mg.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 2.5 mg
Standard Deviation, σ = 0.1 mg
We are given that the distribution of percentage of nitrogen score is unknown.
Formula with sampling:
P( mean of the sample of 100 fertilizers less than 2 mg)
P(x < 2)
Calculation the value from standard normal z table, we have,
Thus, it is impossible that the mean of the sample of 100 fertilizers less than 2 mg.
Answer: Yes, there can be a triangle with the side lengths 10.5 cm, 8.0 cm, and 4.0 cm.
Step-by-step explanation:
We know that triangle inequality says that the sum of any two side of a triangle must be greater to the third side of the triangle.
To check 10.5 cm, 8.0 cm, and 4.0 cm be the side lengths of a triangle, we should check the triangle inequality as.
Thus, the given side lengths satisfy the triangle inequality.
Hence, there can be a triangle with the side lengths 10.5 cm, 8.0 cm, and 4.0 cm.
