A certain manufactured product is supposed to contain 23.2% potassium by weight. A sample of 10 specimens of this product had an average percentage of 23.6 with a standard deviation of 0.3. If the mean percentage is found to differ from 23.2, the manufacturing process will be recalibrated. State the appropriate null and alternate hypotheses.

The null hypothesis is

The alternate hypothesis is

Step-by-step explanation:

Null hypothesis:

The product is supposed to contain 23.2% potassium by weight, which means that at the null hypothesis, we test that this is the correct weight. So

Alternate hypothesis:

If the mean percentage is found to differ from 23.2, the manufacturing process will be recalibrated, which means that we test if the mean differs from 23.2, that is:

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
