4a. The high temperatures for the week in Cincinnati, in degrees

Fahrenheit, were 43, 43, 45, 42, 26, 43, and 45. For numbers 4a–4c,

select True or False to indicate whether the statement is correct.

• True

• False

• True

• False

4c. The high temperatures for the week in Cincinnati, in degrees

Fahrenheit, were 43, 43, 45, 42, 26, 43, and 45. For numbers 4a–4c,

select True or False to indicate whether the statement is correct.
