The required expected population proportion that prefers to shop at places with loyalty cards is between 54.6% and 61.4%.
Given That,
In a survey conducted by a retail store, 58% of the sample respondents said they prefer to shop at places with loyalty cards. if the margin of error is 3.4%.
<h3>What is population proportion?</h3>
A population proportion is defined as the percentage of a population that belongs to a individual category. Certainty gaps are used to evaluate population proportions.
Here, the margin of error is 3.4%.
expected population proportion = 58% ± 3.4%
expected population proportion interval = (58% - 3.4%, 58% + 3.4%)
expected population proportion interval = (54.6%, 61.4%).
Thus, The required expected population proportion that prefers to shop at places with loyalty cards is between 54.6% and 61.4%.

Answer:
C). 0 degrees
Step-by-step explanation:
The given equation is:
-4 + 6 sinx = -4 + 4 sinx
adding 4 on both sides:
4 - 4 + 6 sinx = 4 - 4 + 4 sinx
6sinx = 4sinx
dividing by 2 on both sides, we get:
6sinx/2 = 4sinx/2
3 sinx = 2 sinx
subtracting 2 sinx from both sides we get:
sin x = 0
x = sin⁻¹ (0)
x = 0 degrees
Answer:
3/8
Step-by-step explanation:
There are 3 numbers less than 4 (1, 2, and 3), so the denominator would be 8 for the total number of possibilites and the numerator would be 3.
