Answer:
The standard deviations is
Step-by-step explanation:"
Given mean female height = 64 inches and standard devaiton = 3 inches and 69 inches tall is Sally.
We know the distance of a data point from:
Z = =
So the standard deviations is
1.) C(t) = -0.30(t - 12)^2 + 40
for t = 12: C(12) = -0.30(12 - 12)^2 + 40 = -0.30(0)^2 + 40 = 40°C
For t = 24: C(24) = -0.30(24 - 12)^2 + 40 = -0.30(24 - 12)^2 + 40 = -0.30(12)^2 + 40 = -0.30(144) + 40 = -43.2 + 40 = -3.2°C
4.) F(t) = 9/5 C(t) + 32
for C(t) = 40°C: 9/5 (40) + 32 = 72 + 32 = 104°F
for C(t) = -3.2°C: 9/5(-3.2) + 32 = -5.76 + 32 = 26.24°F
5.) F(t) = 9/5 C(t) + 32 = 9/5 (-0.30(t - 12)^2 + 40) + 32 = -0.54(t - 12)^2 + 72 + 32 = -0.54(t - 12)^2 + 104
Answer:
Claim is False that the incidence of fatigue is greater among those who use Clarinex.
Step-by-step explanation:
Let and be the probabilities of the the incidence of fatigue of those using Clarinex. and placebos respectively
2% of the 1650 treated subjects experienced fatigue who are using Drug Clarinex.
= 1650
Among the 1600 subjects given placebos, 1% experienced fatigue.
= 1600
Claim : The incidence of fatigue is greater among those who use Clarinex.
We will use Comparing Two Proportions
Formula of test statistic :
Substitute the values
test statistic :
test statistic :2.344
refer z table for p value
p value = 0.9904
α = 0.05
Since p value >α
So, we accept the null hypothesis
So, the claim is wrong that the incidence of fatigue is greater among those who use Clarinex.
The answer is B. If you put the information given into a proportion, you will find that Anthony worked for 7.5 hours. When the problem says that his hourly rate is proportional to Carla's, it means that he gets the same amount of money per hour as she does.
