Answer:
The phrase "95% confident" means that there is a 95% confidence that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738).
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.
From the provided data the 95% confidence interval for the population mean parking time of students from within the various college on campus is:
CI = (9.1944, 11.738)
This 95% confidence interval implies that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738) with a specific probability or confidence of 95%.
Thus, the phrase "95% confident" means that there is a 95% confidence that the true mean parking time of students from within the various college on campus is included in the interval (9.1944, 11.738).
You can first make the equations:
6x+4y=548
y-12=x
Here, you can use the substitution method and you get:
6(y-12)+4y=548
6y-72+4y=548
10y=620
y=62
Then there are 62 student tickets and 50 adult tickets.
The answer is £36
7-2 is 5
20 divided by 5 is 4
4 times 2 is 8
4 times 7 is 28
28 add 8 is 36
