You construct a 95% confidence interval for a population mean using a random sample. the confidence interval is 24.9less thanmu
1 answer:
No. It is not that the probability that 
is in the interval is 0.95 rather we are 95% confident that the true mean of the population will be in the stated interval.
Confidence interval does not specify the probability of the occurrence of a population mean in an interval, rather it specifies the level of confidence on the interval of occurrence of the population mean.
Confidence interval does not specify the probability of the occurrence of a population mean in an interval, rather it specifies the level of confidence on the interval of occurrence of the population mean.

Part A: 42.50+0.65x<60
Part B: You can enjoy maximum 26 rides at the fairy tale spectacular.
Step-by-step explanation:
Given,
Admission cost to fair = $42.50
Cost of each ride = $0.65
Amount you can spend = $60
Let,
x be the number of rides you can take.
Admission fair + Cost of each ride*number of rides < Amount you can spend
Part A: write an inequality that represents this situation.
42.50+0.65x<60
Part B: solve the inequality to determine the maximum number of rides you can enjoy at the fairy tale spectacular.
Dividing both sides by 0.65
Rounding off to nearest whole number;
x<27
Less than 27 means, you cannot take 27 rides, therefore,
You can enjoy maximum 26 rides at the fairy tale spectacular.
