A. SAS
Step-by-step explanation:
In the figure attached, the triangles are shown.
The Side Angle Side postulate (SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
In this case, the two sides of triangle ABC are AC and BC and the included angle is ∠C, which are congruent with sides BD and BC and the included angle ∠B from triangle BCD
Answer:
The 90% confidence interval for the percentage of people the company contacts who may buy something is between 10.82% and 14%
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
For this problem, we have that:
90% confidence level
So , z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 90% confidence interval for the percentage of people the company contacts who may buy something is between 10.82% and 14%
