Questions

The statistical process of using samples to estimate population parameters is known as:

1.    Statistical interference

2.    Statistical inference

3.    Statistical confidence

4.       Descriptive statistics

If a researcher wishes to determine whether there is evidence that the mean fasting glucose level in adults with type 2 diabetes is different from 110 mg.dl:

1.     A two-dependent sample t test should be considered

2.     A two-independent sample t test should be considered

3.     A one sample t test should be considered

4.     Either a one sample or two sample dependent samples t test should be considered

Power is defined as:

1.     The probability that you will retain/keep the null hypothesis if it is false

2.     The probability that you will reject the null hypothesis it is true

3.     Determine by your research hypothesis only

4.     The probability that you will reject the null hypothesis it is false

The probability of rejecting the null hypothesis that is true is known as

1.     Type I error

2.     Type Ii error

3.     Statistical Power

4.     Confidence level

Two random samples have sizes of n=100 and n=75 respectively. Which  of the following is true for a 95% confidence interval 

1.     The sample of n=75 has a greater degree of confidence

2.     The sample of n=100 has a greater degree of confidence

3.     The confidence interval for the sample of n=100 is narrower

4.     The confidence interval for the sample of n=100 is wider
