When testing gas pumps for accuracy, fuel-quality enforcement specialists tested pumps and found that 13201320 of them were not pumping accurately (within 3.3 oz when 5 gal is pumped), and 56395639 pumps were accurate. Use a 0.01 significance level to test the claim of an industry representative that less than 20% of the pumps are inaccurate. Use the P-value method and use the normal distribution as an approximation to the binomial distribution. Identify the null hypothesis and alternative hypothesis. A. Upper H 0H0: pequals=0.2 Upper H 1H1: pnot equals≠0.2 B. Upper H 0H0: pless than<0.2 Upper H 1H1: pequals=0.2 C. Upper H 0H0: pnot equals≠0.2 Upper H 1H1: pequals=0.2 D.

When testing gas pumps for accuracy, fuel-quality enforcement specialists tested pumps and found that
normal distribution as an approximation to the binomial distribution.
13201320
of them were not pumping accurately (within 3.3 oz when 5 gal is pumped), and
56395639
pumps were accurate. Use a 0.01 significance level to test the claim of an industry representative that less than 20% of the pumps are inaccurate. Use the P-value method and use the Identify the null hypothesis and alternative hypothesis.
Upper H 0H0:
pequals=0.2
Upper H 1H1:
pnot equals≠0.2
Upper H 0H0:
pless than<0.2
Upper H 1H1:
pequals=0.2
Upper H 0H0:
pnot equals≠0.2
Upper H 1H1:
pequals=0.2
Upper H 0H0:
pequals=0.2
Upper H 1H1:
pless than<0.2
Upper H 0H0:
pgreater than>0.2
Upper H 1H1:
pequals=0.2
Upper H 0H0:
pequals=0.2
Upper H 1H1:
