Answer:
The answer to your question is:
a) P(3) = 5818 mosquitoes
b) 4 days
Step-by-step explanation:
Data
P(t) = Poekt
a)
Po = 1000 mosquitoes
Pt = 1800
t = 1 day
P(3) = ?
1800 = 1000 e1k
1800 / 1000 = e 1k
e 1k = 1.8
1k = In 1.8
k = 0.587
P(3) = 1000 e (0.587)(3)
P (3) = 1000 e 1.761
P(3) = 5818. 2 mosquitoes
b)
P(t) = 10,000
10000 = 1000 e 0.587t
10000 / 1000 = e 0.587t
10 = e 0.587t
In 10 = in e 0.587t
2.3 = 0.587t
t = 3.92 days ≈ 4 days
Answer:
a) X[bar]=93
b)S=5.39
Step-by-step explanation:
Hello!
<em>A simple random sample of 5 months of sales data provided the following information: Month: 1 2 3 4 5 Units Sold: 94 100 85 94 92 </em>
<em />
<em>a. Develop a point estimate of the population mean number of units sold per month. </em>
The variable of interest is:
X: Number of sales per month.
A random sample of n=5 months was taken, for each month, the number of units sold was recorded. To calculate the mean of the sample you have to add all the observed frequencies (Units Sold) by the sample size (n)
X[bar]= ∑X/n= 465/5=93
You can say that, on average, 93 units were sold over the 5-month period.
<em>b. Develop a point estimate of the population standard deviation.</em>
To calculate the sample standard deviation you have to calculate the variance and then its square root:
∑X= 465
∑X²= 43361
S= √29= 5.385≅ 5.39
I hope this helps!
Answer:
The probability is 0.136125
Step-by-step explanation:
45% are in favor of the project, the probability of selecting someone in favor of the project will be 45/100 = 0.45
The probability of selecting someone not in favor of the project = 1 - probability of selecting someone in favor of project = 1-0.45 = 0.55
Now we have 3 people to be chosen at random with exactly one of them favoring the new building project. This means two of them will not favor the building project
Thus the probability here is = the probability of favoring * the probability of not favoring * the probability of not favoring
= 0.45 * 0.55 * 0.55 = 0.136125
