base - 6 (3+3)
side 2 - 13 (9+3)
Triangle perimeter formula - a + b +c
13 + 6 + 13 = 32
Answer:
Decision rule for rejecting is
reject H0 is test statistic <-1.233
Step-by-step explanation:
Given that a sample of 1300 computer chips revealed that 27% of the chips do not fail in the first 1000 hours of their use, as against company literature of 29%
To test this we create hypotheses as
(left tailed test at 10% significance level)
p difference = -0.02
STd error of p =
Test statistic = p diff/std error = -0.1587
For 10% significance level for right tailed test we can reject H0 if
test statistic <-1.645
Decision rule for rejecting is
reject H0 is test statistic <-1.233
Answer: 2495
Step-by-step explanation:
9x + 7(325)-7x = 2495
2x = 220
x = 110 adults and 215 senior citizens
