The 95% confidence interval for the true percent of car owners in this city who received a speeding ticket this year is 44.63% to 49.37%

The formula for calculating the confidence interval is expressed as:

CI = p±z√p(1-p)/n

Given the following parameters

n = 1700

p = 799/1700

p = 0.47

z-score at 95% interval = 1.96

Substitute the given values

CI = 0.47 ±1.96√0.47(1-0.47)/1700

CI =0.47 ±1.96(0.0121)

CI = 0.47±0.0237

CI = 0.47+0.0237, 0.47-0.0237

CI = (0.4463, 0.4937)

Hence the 95% confidence interval for the true percent of car owners in this city who received a speeding ticket this year is 44.63% to 49.37%

A bag contains 6 red balls and blue balls. 4 balls are selected at random. find the probability of selecting 4 red balls.
masya89 [10]

Another way is to note that there are <span><span>(<span>104</span>)</span><span>(<span>104</span>)</span></span> (“10 choose 4”) ways to select 4 balls from a collection of 10. If 4 of those 10 balls are “special” in some way (in this case, “special” = “red”), then the number of ways to choose 4 special balls is <span><span>(<span>44</span>)</span><span>(<span>44</span>)</span></span>. (The factor of <span><span>(<span>60</span>)</span><span>(<span>60</span>)</span></span> is included to convey that, after choosing 4 special balls, we choose none of the 6 non-special balls.) This line of reasoning gives the second expression.
