An asset has 0.5% chance of attack and 20% chance of the attack being successful if it happens. The asset is valued at 25 on a hundred-point scale. If an attack happens and is successful, then the asset loses 75% of its value. It is further given that the give data is 90% accurate. Calculate the risk. give clear handwritten answer!
Part 1 of 3 A researcher was investigating the size of math departments in Texas colleges. She believed the population standard deviation was 1.9. A sample of 42 colleges found their mean was 12.5. Find the 3-decimal small value of the 95% confidence interval of the mean. Part 2 of 3: Find the 3-decimal large value of the 95% confidence interval of the mean. Part 3 of 3: Find the 3-decimal margin of error

Tina catches a 14-pound bass. She does not know the population mean or standard deviation. So she takes a sample of five friends and they say the last bass they caught was 9, 12, 13, 10, and 10 pounds. Find the t and calculate a 95% (α = .05) confidence interval.
When solving a problem related to one sample and the confidence interval of variance. Suppose the sample size is n. What is the degree of freedom we will use?
A health psychologist claims that the more final exams a student has during finals weeks, the more stressed they are. They want to test this experimentally by having 6 students receiving additional finals in their fall semester and then assessing sleep during finals (uį = mu1). Then the same 6 students receive no additional finals in their spring semester and are assessed on their sleep during finals (u2 = mu2) and they want to assess if the difference in sleep with additional finals relative to no additional finals with mu1 - mu2. µ1 = mu1 = Additional finals and µ2 = mu2 = No additional finals They get the following data: Additional Final Exams No Additional Final Exams 88 66 76 43 54 59 63 72 53 58 84 48 What would be the mean difference (i.e., the numerator of your t statistic)? Please compute and report to 4 decimal places.
34% of CSU students participate in the Statistics Games while they attend CSU. You take a random sample of 40 students. You want to determine the probability that more than 15 of them have participated in the Statistics games. Since the conditions are met, you decide to use the Normal model to find your answer. What is the mean and standard deviation of the sampling distribution?

K Do freshmen spend significantly more time on social media than other class ranks? A recent study investigated the amount of time per day freshmen, sophomores, juniors, and seniors spent on social media while doing schoolwork. The students surveyed were U.S. residents from a 4-year, public, primarily residential institution. The accompanying computer output shows the mean time each cohort spent on social media and an ANOVA table. Construct a 95% confidence interval to compare the population mean time spent per day on social media between freshmen and seniors. Click the icon to view the summary statistics and ANOVA table.
