Expert Solution

Step 1

The question is about estimate of std. error of diff. between two popl. proportions

Given :

Total no. of voter pooled for player " M " ( n₁ ) = 300

No. of voter in favor of player " M " ( x₁ ) = 210

Total no. of voter pooled for player " R " ( n₂ ) = 400

No. of voter in favor of player " R " ( x₂ ) = 250

To find :

Std. error of ${\bar{p}}_{1} - {\bar{p}}_{2}$

Cloud seeding, a process in which chemicals such as silver iodide and frozen carbon dioxide are introduced by aircraft into clouds to promote rainfall was widely used in many years. Recent research has questioned its effectiveness. An experiment as performed by randomly assigning 52 clouds to be seeded or not. The amount of rain generated was then measured in acre-feet. The box plot of the data for the seeded and unseeded clouds are shown in the figure. Which statement best interprets the box plot. Boxplot of Seeded, Unseeded 3000 f 2500어 2000 - 1500 - 1000 - 500- Seeded Unseeded a. Cloud seeding is somewhat effective in promoting rainfall because of the greater mean b. Outliers for both seeded and unseeded data may prove data on the effectiveness of cloud seeding is insufficient c. Extreme outliers are evident in the seeded data and has greater variance O d. There's a greater mean and greater dispersion in the seeded data. Both plots show outliers Data
