3.5. Each of the following measurements is a rounded value. We have no way of knowing the exact value that was rounded to obtain these rounded values. For each, i) state the range of possible exact values; ii) stating the absolute value of the maximum possible measurement rounding error that may have resulted from the rounding; and iii) state the minimum and maximum possible relative measurement error as a percent to two significant digits.

a. 0.02 ft b. 0.07 ft c. 2.634E+02 km d. 9.167E+02 km

Consider a study design in which we have collected multiple response measurements at each value of the predictor. Suppose we have ni observed responses at each value of xi, indexed by i=1,…,m, and yij corresponds to the j-th observation on the response, j=1,…,ni for the i-th value of the predictor. This means we have m unique predictor values, and ni response measurements for each of the m values of the predictor. In this situation, it is possible to create a...

We are conducting a one-way between groups ANOVA. We have 50 people in each condition. Each person rates how much they like their assigned food (pizza, burger, or taco) on a scale of 1 to 5 (1 = hate this food, 5 = favorite food ever). We run a hypothesis test and find a significant statistic. What does this mean? Calculate all the appropriate HSDs for the following groups: Pizza Mean: 2.3; Burger Mean: 4.5; Taco Mean: 3.7; Standard Error...

We want to study the zinc concentration from a river. We have a sample of measurements taken in 25 different locations in a river with sample mean x = 3 and population standard deviation σ = 0.3. The population is normally distributed. 1. Find the 95% and 99% confidence intervals for the mean zinc concentration in the river. 2. Is the following statement correct? “If we repeat the same experiment multiple times and each time calculate the two confidence intervals...

Suppose we have a box model representing a die: [1,2,3,4,5,6] with a mean of μ=3.5 and a standard deviation of σ=1.708. If we do 88 rolls of the die what will our expected value and standard error be for our sampling sum, respectively? Suppose we have the following box representing our population [0, 1, 1, 2, 3, 5] with μ=2.0 and σ=1.79. If we sample or draw from this population 35 times, what is the probability that the sum exceeds...

1. This is especially valuable when we have subsets of measurements that are highly correlated. In that case it provides few variables that are weighted linear combinations of the original variables that retain the explanatory power of the full original set. A. Correlation analysis B. Affinity analysis C. Variance Analysis D. Principal Component Analysis 2. These are very helpful for data reduction. The information they convey can assist in combining categories, in choosing the variables to remove, and in assessing...
