Step-by-step explanation:
9^2+11^2=x^2
81+121=202
Probability that a customer ordered a hot drink given that he or she ordered a large, P( Hot | Large) = 0.22
<h2>Conditional Probability</h2>
The total number of customers' orders, N(Total) = 100
Number of people that ordered a hot and large drink together,
N(Hot |Large) = 22
Probability that a customer ordered a hot drink given that he or she ordered a large, P( Hot | Large) = N(Hot |Large) / N(Total)
P( Hot | Large) = 22/100
P( Hot | Large) = 0.22
Probability that a customer ordered a hot drink given that he or she ordered a large, P( Hot | Large) = 0.22

Answer:
There is 95% confidence that the true value of the population proportion is included in the interval (0.33, 0.45).
Step-by-step explanation:
The (1 - <em>α</em>)% confidence interval for population parameter implies that there is a (1 - <em>α</em>) probability that the true value of the parameter is included in the interval.
Or, the (1 - <em>α</em>)% confidence interval for the parameter implies that there is (1 - <em>α</em>)% confidence or certainty that the true parameter value is contained in the interval.
The 95% confidence interval for the population proportion is calculated to be 0.39 ± 0.06.
The interval is:
CI = (0.33, 0.45)
This confidence interval implies that, there is 0.95 probability that the true value of the population proportion is included in the interval (0.33, 0.45).
Or, there is 95% confidence that the true value of the population proportion is included in the interval (0.33, 0.45).
