Define p as the proportion of individuals who leave one space after a sentence.
Provided: Sample size: n= 525
Number of respondents indicating they leave one space: 440
Thus, the sample proportion is: 
The z-score for a 90% confidence interval is: 1.645
The formula for determining the confidence interval:
Consequently, a 90% confidence interval for the proportion of people who leave one space after a period is: (0.8115, 0.8645)
