Answer: Null hypothesis :
Alternative hypothesis :
Step-by-step explanation:
Given claim : The proportion of U.S. adults age 25 or older who smoke :
A researcher suspects that the rate is lower among U.S. adults 25 or older who have a bachelor's degree. i.e.
Since the null hypothesis is a fact checked by the researcher or the experimenter that always contains a equals to sign.
∴ Null hypothesis :
Alternative hypothesis :
Answer:
Step-by-step explanation:
3n+8=35
subtract 8 on both sides
3n=27
n=9
Answer:
x = 91
Step-by-step explanation:
The opposite angles of an inscribed quadrilateral are supplementary, that is
∠ A + ∠ C = 180, thus
x + 89 = 180 ( subtract 89 from both sides )
x = 91
