Assume that a sample is used to estimate a population proportion p. Find the margin of error E (or EBP) that corresponds to the given statistics and confidence level. Round the margin of error to four decimal places. 95% confidence, n= 320, X = 60

Use the given data to find the minimum sample size required to estimate the population proportion.

a. Margin of error: 0.004; confidence level: 95%; p and q unknown.
b. Margin of error: 0,009; confidence level: 99%; P and unknown
c. Margin of error: 0.01; confidence level: 95%; from a prior study, p is estimated by the decimal equivalent of 52%

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
