4. Gabriela is records their total weight, w, in grams. weighing quarters on a scale. She weighs various numbers of quarters, n, and number of quarters, n 4 10 24 total weight, w (grams) 22 55 132 (a) Find the ratio of the weight of the quarters to the number of quarters for all three columns of the table. Use long division. Express your answer using decimals. 4:22 22/40 (b) Explain why the ratios (quotients) in (a) show that there is a proportional relationship between the number of quarters and the weight? Explain. (c) What is the constant of proportionality (d) If Gabriela placed 30 quarters on the between the two variables? What does it scale, what would the weight, w, be? represent? (e) Based on (d), try to write an equation that relates the weight, w, of the coins based on the number of coins, n, and the constant of proportionality.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
