In a survey of 500 U. S. adults, 45% of them said that lounging at the beach was their "dream vacation.’ Assuming this to be a simple random sample of U. S. adults, the lower confidence limit of the 95% confidence intervals for the proportion of U. S. adults who consider lounging at the beach to be their dream vacation would equal to:

0.4064

Step-by-step explanation:

Number of adults sampled (n) = 500 strikes

Z-score for a 95% confidence interval (Z) = 1.960

Proportion that said that lounging at the beach was their "dream vacation.’ (p) = 0.45

The lower confidence bound (L) for a confidence interval of a proportion is determined by the following expression

 Applying the given data:

The lower confidence bound for the proportion of U.S. adults who consider lounging at the beach to be their dream vacation would equal to 0.4064.

560

hope this : )

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
