<span>We first need to figure out how much insurance Susan pays annually. For every $100, she pays 30 cents. Well, let's pretend that we have her entire home's value in 100 dollar bills. There will be 4830 bills. On each of those bills, she will pay 30 cents. If we multiply .30 x 4830 we get $1449. This is how much she pays all year- to find out how much she pays each month, we divide by 12. This gives us 120. 75. We include this on her monthly mortgage payment: 120.75 + 2128 and we get A) 2248.75.</span>
Using the normal distribution, there is a 0.5398 = 53.98% probability that a randomly selected cyclist will take at least 2.45 hours to complete the race.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean 
and standard deviation 
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
The mean and the standard deviation are given, respectively, by:
The probability that a randomly selected cyclist will take at least 2.45 hours to complete the race is <u>one subtracted by the p-value of Z when X = 2.45</u>, hence:
Z = -0.1
Z = -0.1 has a p-value of 0.4602.
1 - 0.4602 = 0.5398.
0.5398 = 53.98% probability that a randomly selected cyclist will take at least 2.45 hours to complete the race.

Answer:
Categorical is the correct answer to this question.
Step-by-step explanation:
The variable class standing is "Categorial".
- As a categorical variable, it is a factor that can accept one of a small, and typically set, range of additional values, assigned each person, and another unit of measurement to a specific group or marginal class on the grounds of some long-lasting.
- The data obtained may be either prescriptive or numeric.
- Numbers also make no sense when you allocate significance to certain numbers.
- Categorical data will help you go there. Classic data is when statistics are obtained in classes or categories.
