Answer:
The hypothesis formulae will be
H0 : p = 0.5
Ha : p < 0.5
we will reject H0.
Step-by-step explanation:
Number of responses ( n ) = 1017
percentage( p ) = 39% = 0.39
significance level ( ∝ ) = 0.05
P0 = 50% = 0.5
<u>Test the claim that fewer than half of all teenagers feel the pressure </u>
The hypothesis formulae will be
H0 : p = 0.5
Ha : p < 0.5
Perform the test statistic
Test statistic ( Z ) = -6.957
P-value < 0.05 we will reject H0.
