A random sample of 1000 people was taken. Four hundred fifty of the people in the sample favored Candidate A. The 95% confidence
KatRina [158]

Answer:

The 95% confidence interval would be given (0.419;0.481).

Step-by-step explanation:

Data given and notation  

n=1000 represent the random sample taken    

X=450 represent the people in the sample favored Candidate A

\hat p=\frac{450}{1000}=0.45 estimated proportion of people in the sample favored Candidate A  

\alpha=0.05 represent the significance level

Confidence =0.95 or 95%

p= population proportion of people in the sample favored Candidate A

Solution to the problem

The confidence interval would be given by this formula

\hat p \pm z_{\alpha/2} \sqrt{\frac{\hat p(1-\hat p)}{n}}

For the 95% confidence interval the value of \alpha=1-0.5=0.05 and \alpha/2=0.025, with that value we can find the quantile required for the interval in the normal standard distribution.

z_{\alpha/2}=1.96

And replacing into the confidence interval formula we got:

0.45 - 1.96 \sqrt{\frac{0.45(1-0.45)}{1000}}=0.419

0.45 + 1.96 \sqrt{\frac{0.45(1-0.45)}{1000}}=0.481

And the 95% confidence interval would be given (0.419;0.481).

We are confident (95%) that about 41.9% to 48.1% of the people are favored Candidate A.

A trinket factory can produce 3000 trinkets per day the. warehouse has a capacity of 50000 trinkets .currently there are 8000 tr
nata0808 [166]

Answer:

14 days

Step-by-step explanation:

Since there are already 8000 trinkets in the warehouse, this means that we need to find the number of days it will take for the factory to create 42,000 trinkets which would cause the warehouse to max out it's capacity.

50,000 - 8000 = 42,000 trinkets

Since the factory can produce 3000 trinkets per day, we simply need to divide 42,000 by 3000 to get the number of days before the warehouse is at max capacity

42,000 / 3000 = 14 days

Therefore, it will take 14 days for the warehouse to be filled

andreyandreev [35.5K]

Answer:

Option D. h-(1/2)=(3/4)

Step-by-step explanation:

Let

h-----> the number of hours Emma walked her dog

we know that

The equation that represent the situation is equal to

h=(1/2)+(3/4)

Subtract (1/2) both sides

h-(1/2)=(3/4)
