Answer:
Step-by-step explanation:
CE × ED = AE × EB
17 CE = 14 × 18
CE = ≈ 14.8
Answer:
Step-by-step explanation:
Let x be the normal body temperature
X is N(99, sigma)
Sample mean x bar = 98.2 and s = 0.63
Margin of error = Z critical * 0.63 = 1.95 *0.63 = 1.2285
It is safe since 1.5 <1.96 critical value of z at 95%
the answer would be: y - 1/2 ≤ -3/2
