A company that produces cell phones claims its standard phone battery has a mean lifetime of 35 hours. In order to investigate the company's claim, a consumer advocacy group takes a sample of 75 batteries and finds a mean lifetime of 34.45 hours with a standard deviation of 2.25 hours. At a 1% level of significance, is there evidence for the consumer advocacy group to conclude that the mean lifetime of the batteries is lower than claimed?

BLANK #1: Which type of distribution should be used to calculate the probability for this question? ***ANSWER "NORMAL"or "T"

BLANK #2: Which of the following options are the appropriate hypotheses for this question:

A) H₀: = 34.45 hrs H₁: > 34.45 hrs

B) H₀: = 35 hrs H₁: > 35 hrs

C) H₀: = 34.45 hrs H₁: <34.45 hrs

D) H₀: = 35 hrs H₁: < 35 hrs

E) H₀: = 34.45 hrs H₁: 34.45 hrs

F) H₀: = 35 hrs H₁: 35 hrs

BLANK #3: What is the p-value of this sample?

BLANK#4: Based on this sample,at a 1% level of significance, is there evidence for the consumer advocacy group to conclude that the mean lifetime of the batteries is lower than claimed?***ANSWER "YES" OR "NO"
