Answer:

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

[tex]H_0: p = 0.10\\H_a: p >0.10[/tex]

(right tailed test)
