Question

1)A confidence interval is used for estimating a population parameter. TRUE/FALSE
2)A confidence interval always captures the sample statistic.TRUE/FALSE
3) A confidence interval always captures the population parameteTRUE/FALSE
4)When constructing a confidence intervals we should always use Z-critical values.TRUE/FALSE
5) The margin of error determines the center location of the confidence interval.TRUE/FALSE
6)In general, we would like to have a precise confidence interval while having a high level of confidence.TRUE/FALSE
7)When constructing a confidence interval for a proportion we need a large sample size. Read answers carefully.
Group of answer choices
False – The size of the sample is not important
True – n*(p-hat) OR n(q-hat) need to be at least 10
True – Both n*(p-hat) AND n(q-hat) need to be at least 10

The  solutions  for the given conditions are;  1. True  2. True  3. False  4. False  5. False  6. True  7. True      1) For estimating a population parameter, a confidence interval is used.    TRUE  → CI is used for estimating a  population parameter . But, it can also be used to estimate the sample statistic.  2) The sample statistic is always captured by a  confidence interval .     TRUE  → CI is calculated using the sample statistic.  3) The population parameter is always captured by a confidence interval.    FALSE  → There is a type 1 error possibility.  4) Z-critical values should always be used when creating confidence intervals.    FALSE  → Z stat is used only in a normal distribution with sizes>30. Else, it is recommended to use a t distribution.  5) The center of the confidence interval is determined by the  margin of error.     FALSE  → ME determines the maximum deviation from the center at a given confidence level  6) In general, we would like to have a high level of confidence and a precise confidence interval.    TRUE  → This is attainable when we increase the sample size.  7) A large sample size is required to create a proportion's confidence interval.    TRUE  → Along with the large sample, we also need to have np and nq at least 10.        To learn more about  confidence interval  click here:  brainly.com/question/24131141  #SPJ4

Which expression shows the factors of 9×2 3x − 2? a. (3x − 1)(3x − 2) b. (3x 1)(3x − 2) c. (3x 2)(3x − 1) d. (9x − 2)(x 1)

Consider the quadratic equation x2 10x 27 = 0. completing the square leads to the equivalent equation (x )2 = .
