Directions: Determine the parameter to be tested in the given problems below. 1. An electric lamps manufacturer is testing a new method of producing lamps that will be considered acceptable in a normal population with an average life of 2,600 hours and a standard deviation equal to 350. A sample of 80 lamps produced by this method has an average life of 2,630 hours. Can the hypothesis of validity for the new manufacturing process be accepted with a risk equal to or less than 5%? 2. A car dealer claims that the average price of Honda Vios is at least ₱662,000.00. A client suspected that the claim is incorrect and found that random sample of 15 similar vehicles has the mean price of ₱640,000.00 and standard

Question
Directions: Determine the parameter to be tested in the given problems
below.
1. An electric lamps manufacturer is testing a new method of producing
lamps that will be considered acceptable in a normal population with an
average life of 2,600 hours and a standard deviation equal to 350. A
sample of 80 lamps produced by this method has an average life of 2,630
hours. Can the hypothesis of validity for the new manufacturing process
be accepted with a risk equal to or less than 5%?
2. A car dealer claims that the average price of Honda Vios is at least
₱662,000.00. A client suspected that the claim is incorrect and found that random sample of 15 similar vehicles has the mean price of
₱640,000.00 and standard deviation of ₱ 24,000.00. Is there enough
evidence to reject the dealer’s claim at ? = 0.05?
