output table are not included.

Hand calculations for the standard error of the mean are not

included.

Hand calculations for a 95% confidence interval for Age and

SPSS output screenshots verifying the answer are not

included.

Interpretation of the confidence interval for age, explanation

of the three pieces of information needed to calculate the

Calculation of probability of an individual being 60 years or

older, including associated hand calculations and screenshots,

is incomplete or incorrect.

Mean and standard deviation for Age and associated Excel

output table are incomplete or incorrect.

Hand calculations for the standard error of the mean are

incomplete or incorrect.

or incorrect.

incomplete or incorrect.

Frequent and repetitive mechanical errors distract the

reader. Inconsistencies in language choice (register) or word

choice are present. Sentence structure is correct but not

varied.

Calculation of probability of an individual being 60 years or

older, including associated hand calculations and screenshots,

is partially complete and correct.

Mean and standard deviation for Age and associated Excel

output table are partially complete and correct.

Hand calculations for the standard error of the mean are

partially complete and correct.

Hand calculations for a 95% confidence interval for Age and

SPSS output screenshots verifying the answer are partially

complete and correct.

Interpretation of the confidence interval for age, explanation

of the three pieces of information needed to calculate the

confidence interval, and discussion of the age cut-off are

included but lack details and supporting information.

Some mechanical errors or typos are present, but they are

not overly distracting to the reader. Correct and varied

sentence structure and audience-appropriate language are

employed.
