A 98% confidence interval for the mean of a population is computed from a random sample and found to be (10.5, 12.9).lt may be concluded that * O There is a 0.98 probability that the sample mean is between 10.5 and 12.9. There is a 0.98 probability that the true population mean is within one margin of error of the sample mean of 11.7. There is a 0.98 probability that the population mean is between 10.5 and 12.9.

Help me please I'm a bit confused . It's number 2 that I'm asking
Transcribed Image Text:O A Type Il error could have occurred.
2. A 98% confidence interval for the mean of a population is computed from a
random sample and found to be (10.5, 12.9).lt may be concluded that
There is a 0.98 probability that the sample mean is between 10.5 and 12.9.
There is a 0.98 probability that the true population mean is within one margin of error
of the sample mean of 11.7.
There is a 0.98 probability that the population mean is between 10.5 and 12.9.
O There is a 0.02 probability that the population mean is outside the interval.
None of the other choices.
5. When using a statistical test of significance, the result is not considered
statistically significant if*
A Type Il error was likely to occur.
O The P-value is less than the significance level.
