Answer:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Step-by-step explanation:
For this case we have the following data given:
Demand (x): 10,20,30,40,50,60,70,80,90,100
Price (y): 141 , 133,126, 128,113,97, 90, 82,79,53
We want to construct a linear model like this:
For this case we need to calculate the slope with the following formula:
Where:
So we can find the sums like this:
With these we can find the sums:
And the slope would be:
Nowe we can find the means for x and y like this:
And we can find the intercept using this:
So the line would be given by:
Answer: The probability that exactly 2 insects will survive = 0.2501
Step-by-step explanation:
Given: A certain insecticide kills 80% of all insects in laboratory experiments.
The probability that a particular insect survives= 1-0.80=0.20
Sample size: n=14
Binomial probability distribution:
, where x= number of successes , p=probability of success in each trial, n= sample size.
The probability that exactly 2 insects will survive =
Hence, the probability that exactly 2 insects will survive = 0.2501
