Gary is studying the prevalence of regional dialects. He surveyed 351 people in a region and asked what words they used for cert

chubhunter [2.5K]

Answer:

Confidence interval = ( 0.7991, 0.8647 )

Step-by-step explanation:

Sample size = n = 351

number of successes = X = 292

Sample proportion = P = $\frac{X}{n}$

= $\frac{292}{351}$

= 0.831908831

confidence interval = 90%

Critical Z value = 1.6449 [by using excel]

Confidence interval = P ± Z $\sqrt{P\frac{(1-P)}{n}}$

Where P = Sample proportion

Z = critical value

n = sample size

Confidence interval = 0.831908831 ± 1.6449 $\sqrt{0.831908831\frac{(1-0.831908831)}{351}}$

= 0.831908831 ± 1.6449 × 0.0200

= 0.831908831 ± 0.032898

Lower limit = 0.831908831 - 0.032898 = 0.7991

Upper limit = 0.831908831 + 0.032898 = 0.8647

Confidence interval = ( 0.7991, 0.8647 )
