As part of his semester project, a BYU-Idaho Introductory Statistics student calculates a 95% confidence interval for the true p
lyudmila [28]

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.

Suppose that your test statistic is t(99 ) = -2.8888. Round the test statistic to two places after the decimal point.
Scrat [10]

Answer:

t(99)= -2.89

Step-by-step explanation:

-To places after the decimal point is equivalent to rounding off to the nearest hundredth.

-To round off to the nearest hundredth, we check the thousandths digit:

  • If the thousandths digit is less than5, we round down to the previous hundredth.
  • If the thousandths digit is greater than 4, we round up to the next hundredth:

Hence,-2.8888\approx-2.89
