A seller has acquired 120 randomly selected items from a vendor for his stores. He has an allowance of 10% for damaged items. Of the 120 items acquired from the vendor, the seller found that 15 are damaged. He decides to test whether the population proportion of the vendor's items exceeds the seller's allowable limit. State the null and alternative hypotheses.

Step-by-step explanation:

Given that a seller has acquired 120 randomly selected items from a vendor for his stores. He has an allowance of 10% for damaged items. Of the 120 items acquired from the vendor, the seller found that 15 are damaged.

Population proportion= 0.10

Sample proportion = 15/120 = 0.125

To test whether the population proportion of the vendor's items exceeds the seller's allowable limit,

the hypotheses would be

(right tailed test)

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
