Answer all pf them thank you
It gives a range of values within which the parameter value possibly falls. Interval Sampling O b. Range Estimation O c. Confidence Interval Od. Point Estimate The shape of the T-distribution curve is wider than the normal curve because it has higher variance Ob. the mean is also located at the end of the curve Oc. it has more sample size the curve is represented by degrees of freedom T-distribution is used when O a. the sample standard deviation is given and the population size is less than 30 Ob. the population standard deviation is unknown and the sample size is greater than 30 the sample size is greater than 30 and the population variance is known the population standard variance is unknown and the sample size is less than 30

Which of the following statements is TRUE? The larger the size of the sample, the greater is the length of the confidence interval. Ob. The smaller the confidence level, the greater is the length of the confidence interval. The larger the size of the sample, the lesser is the length of the confidence interval. Od. The larger the confidence level, the lesser is the length of the confidence interval. Z-distribution is used when the population standard deviation is unknown and the samplle size is greater than 30 Ob. the population standard variance is unknown and the sample size is less than 30 Oc. the sample standard deviation is given and the population size is less than 30 Od. the sample size is greater than 30 and the population variance is known This refers to the degree of certainty that the true population parameter falls within the constructed interval estimate. Degrees of certainty Ob. Confidence interval O c. Degrees of freedom Od. Confidence level
