Answer:
a. There's a 95% chance that the true proportion is in the confidence interval.
Step-by-step explanation:
When we want to estimate a property of a population (a population's parameter), without surveying the population, we use samples.
Then, with the information of the samples we can calculate the statistics and infere properties about a population. This inferences obviously came with some uncertainty, depending on the properties of the sample and specially the sample size.
When we talk about confidence intervals, we use the statistic of the sample (in this case, the mean) to estimate a range of values it is expected to find the true mean of the population. The width of this interval depends on the sample standard deviation and the sample size.
The value of the confidence interval (95%, 99%, etc) represent the probabilty that the true mean is within this interval.
Answer:
Ashley can type 475 more words than Tristan in 95 minutes.
Step-by-step explanation:
1. Multiply the amount of words Tristan can type per minute (57) times 95 to get 5,415 typed words in 95 minutes.
2. Multiply the amount of words Ashley can type per minute (62) times 95 to get 5,890 typed words in 95 minutes.
3. Next you subtract Tristan's total amount, 5,415 from Ashley's total amount to get the answer: Ashley can type 475 more words than Tristan in 95 minutes.
