14 of 25 (6 complete) This Test: 25 p po of a t show had a 10 share, that among 6000 monitored households with TV sets in use, 10% of them were bred to this program that among the households with TV sets in use, less than 15% were tuned into the program identify the Use a 0.01 significance level to test the claim of an a Use the P-value method. Use the normal distribution as an approximation of the binomiall distribution 0 A. Ho-p:0.15 O B. Ho p 0.85 H p>0.85 O D. Ho p-0.85 H, pc085 OF. Ho p 0.15 H, p

Explanation / Answer

The statistical software output for this problem is:

One sample proportion summary hypothesis test:
p : Proportion of successes
H0 : p = 0.15
HA : p < 0.15

Hypothesis test results:

Hence,

Hypotheses: Option F is correct.

z = -10.85

P - value = 0.0000

Reject the null hypothesis. There is sufficient evidence to conclude that the population proportion is less than 15%

Proportion Count Total Sample Prop. Std. Err. Z-Stat P-value p 600 6000 0.1 0.0046097722 -10.846523 <0.0001
