The length of the infinite zigzag path is 1
<h3>How to determine the length</h3>
Note that the infinite zigzag path is embedded in an isosceles triangle
Using angle π/4, we have that
Tan π/4 = opposite/ adjacent
To find the longer part 'y', use the Pythagorean theorem
The length of the infinite zigzag path is the same as the length of the longer part of the triangle which equals 1.
Thus, the length of the infinite zigzag path is 1

Answer:
H0:p1=p2; Ha:p1≠p2, which is a two-tailed test.
Step-by-step explanation:
We formulate our hypotheses as
H0:p1=p2; Ha:p1≠p2, which is a two-tailed test.
Supposing the probability or proportion of the first survey is equal to the probability or proportion of the second survey. This will be the null hypothesis and the alternative hypotheses would be that these two proportions or probabilities are unequal.
This is a two tailed test.

As per given , we have
n= 88
Population standard deviation :
Critical value for 98% confidence interval : n
Margin of error :
98% confidence interval :
The 98% confidence interval (34.36, 38.64) found by normal distribution with the appropriate calculations for a standard deviation that is known is narrower than the interval (28.7,44.3) found by the t-distribution (population standard deviation is unknown) .
