A study is conducted to determine how long a person will wait on hold on a telephone call before hanging up. A sample of 1000 pe
klasskru [66]

Answer:

The estimate of a range of plausible values for the true proportion of people that will not wait more than one minute on hold at a 95% confidence level is

Confidence interval = (549.404, 610.596)

Step-by-step explanation:

We will be finding the confidence interval at 95% confidence level.

The proportion of people that hang up the phone in the first minute of waiting

= P = (580/1000) = 0.58

We can then calculate the standard deviation of the distribution of sample means = σₓ = √[np(1-p)]

where n = sample size = 1000

σₓ = √[np(1-p)] = √[1000×0.58×0.42] = 15.61

Confidence interval = (Sample mean) ± (Margin of error)

Sample mean = 580

Margin of Error = (critical value) × (standard deviation of the distribution of sample means)

Critical value = 1.960

Even though we do not have information on the population mean and standard deviation, we can use the z-distribution's z-score for 95% confidence interval instead of the t-distribution's t-score since the sample size is 1000.

Margin of error = 1.960 × 15.61 = 30.596

Confidence interval = (Sample mean) ± (Margin of error)

Confidence interval = 580 ± 30.596

Confidence interval = (549.404, 610.596)

Hope this Helps!!!

Chelsea and her friends are making small fruit baskets for their neighbors. They have 90 pears, 45 peaches, and 75 apples. What
iVinArrow [24]

Answer:

15 baskets

Step-by-step explanation:

This question is a GCF question

The first step would be to find the factors of 45, 75 and 90

The factors of 45 are: 1, 3, 5, 9, 15, 45

The factors of 75 are: 1, 3, 5, 15, 25, 75

The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90

The greatest common factor is 15.

Therefore, the greatest number of baskets they can make if each basket has the same number of pears, the same number of peaches, and same number of apples, with no fruit leftover is 15 baskets
