a tortoise is walking in the desert. It walks for 9.6 meters at a speed of 6 meters per minute. For how many minutes does it walk?
You collect a random sample of 50 children and compute , the average height in inches. The sample standard deviation (s) equals 10. Suppose the true mean height μ equals 45 inches. For which of the following values of will a 95% confidence interval contain the true mean μ? I. = 47.5 inches II. = 50 inches III. = 42 inches
You conduct a poll of FIU students in order to determine the percentage of students (p) who agree with the statement “Hot-dogs are one of my favorite foods”. In your poll, you find that 80 out of 100 students agree. You conduct a two-sided hypothesis test where H0: p = 0.7, where p is the proportion of students whose favorite food is hot dogs. Which of the following statements are true: I. You reject the null hypothesis when α = 0.05 II. You reject the null hypothesis when α = 0.01 III. The test statistic (Z) equals Z = +1.5
You collect data on N = 25 student weights and find that the average student weight in your sample is 135 pounds. The sample standard deviation (s) is 5 pounds. You conduct a two-sided hypothesis test where H0: μ = 134 pounds. Which of the following statements are true: I. You reject the null hypothesis when α = 0.05 II. You reject the null hypothesis when α = 0.01 III. The test statistic (T) equals T = +1
How much must be invested today, March 1, 2024 to make equal quarterly withdrawals due for $2,500 each during 2022, if deposits earn interest at 8% CT?
For the function f(x), the real number a where f(a)=a is called the fixed point of the function f(x). Show that when f(x) is continuous and differentiable for all real numbers x, if f’(x)≠1, then f(x) has at most one fixed point.
Example 2: The head of the faculty library states that the average number of students who visit it per day is 350. To confirm or not this assumption, the number of attendees for 30 days is recorded and it is found that the average was 372.6. If the standard deviation of 52.414 and a significance level of 0.05 is considered, say whether you would support what the head of the library says.
