In the next five questions, we'll work with two different species of bears: polar bears and Kodiak bears. We will assume that:

- The histogram of weights for male polar bears can be approximated by a normal curve with an average of 1108 lbs and a standard deviation (SD) of 128 lbs.
- Similarly, the histogram of weights for male Kodiak bears can be approximated by a normal curve with an average of 990 lbs and an SD of 110 lbs.

This information will be provided in each of the following questions, but you may benefit from storing the values of the average and SD as objects in R, clearly identified for each bear type, as you will need those precise values repeatedly.

Answer :

Final answer:

To calculate the probability of a random male polar bear weighing more than 1200 lbs, we can use the z-score formula and a standard normal distribution table or calculator.

Explanation:

The subject of this question is Mathematics and the grade level is High School.

To calculate the probability of a random male polar bear weighing more than 1200 lbs, we can use the z-score formula: z = (x - mean) / standard deviation. Once we find the z-score, we can use a standard normal distribution table or a calculator to find the probability. In this case, we need to find the area to the right of the z-score.

For example, if we want to find the probability of a random male polar bear weighing more than 1200 lbs, with a mean of 1108 lbs and a standard deviation of 128 lbs, we can calculate the z-score: z = (1200 - 1108) / 128 = 0.719. Using a standard normal distribution table or a calculator, we can find that the probability is approximately 0.236 or 23.6%.

The mean of the histogram of weights for male polar bears is 1108 lbs, and the standard deviation is 128 lbs. The mean of the histogram of weights for male Kodiak bears is 990 lbs, and the standard deviation is 110 lbs.

We may gain from storing the values of the mean and standard deviation as objects in R, with each bear type's precise values clearly defined.The mean of a probability distribution is calculated by multiplying each outcome by its probability, adding up all of these products, and then dividing the total by the number of outcomes in the sample. The arithmetic average of a data set is the average, or mean, of the data set; the mean is calculated by dividing the sum of all the data points by the number of data points.

For a normal distribution, the arithmetic mean and standard deviation characterize the distribution. The mean specifies the distribution's center, whereas the standard deviation specifies the distribution's width.

If we have a normally distributed population, we may use this information to answer questions about the population and estimate the likelihood of particular outcomes.

We use the properties of a standard normal distribution (a normal distribution with a mean of zero and a standard deviation of 1) to estimate the likelihood of a sample outcome falling in a certain range.
