Answer:
150 seconds
Step-by-step explanation:
Remember that
To convert miles to feet multiply by 5,280
To convert hours to seconds, multiply by 3,600
step 1
Convert the average rate of miles per hour to feet per second
step 2
Find out how many seconds does the ride take to travel this length of track
we know that
The length of the track is 3,300 ft
so
Divide the total length of the track by the speed
The Confidence interval for 95% who believes that the local businesses overcharge = (0.7026, 0.7574)
<h3>
What is meant by confidence interval?</h3>
The range of values we see in our sample and hope to identify the value that most closely represents the population are referred to as a confidence interval.
<h3>According to the given information:</h3>
Sample size n = 1000
73% of town residents believed that local businesses overcharged for their products over 1000 resident.
= (1000/100) x 73
= 730
Sample proportion p = 730/1000
= .73
q = 1-p = 0.23
Std error of proportion = √(pq/n)
= √((.73*0.27)/1000)
= 0.0140
95% Z critical value = 1.96
Margin of error = 1.96*0.0140
= 0.0274
Confidence interval = sample proportion ±margin of error
(0.7026, 0.7574)
