Rini plans to remove M&Ms from her bag one at a time until she gets her first red. How many M&Ms should she expect to remove?The averrage gasoline prrice at Chevvron was $3.12 per gallon lastt month. Due to the recent nation-wide gas price drop, the chiief marketing officer of Chevvron believes that there has been a significant reduction in the average gas pricce. In orrder to test hiis belief, he randdomly selected a sample of 36 of Chevvron gas stations and found the average gas price of these stations was $3.06. Assume that the population standard deviation of the population is $0.12, and the significance level (α) is 5%. A. Formmullate the null and the alternative hypotheses: Null: mu ≤ 3.06; Alternative: mu > 3.06 Null: mu = 3.06; Alternative: mu ≠ 3.06 Null: mu ≥ 3.12; Alternative: mu < 3.12 Null: mu = 3.12; Alternative: mu ≠ 3.12 Null: mu ≤ 3.12; Alternative: mu > 3.12 Null: mu ≥ 3.06; Alternative: mu < 3.06 B.

Perimeter Shot - A perimeter shot, also known as a mid-range shot, is a jump shot or general field goal attempt that an offensive player can take inside of the three-point line and is worth 2 points. To practice this, Piel has to choose four different shooting spots among the five different spots in where he is comfortable of shooting. In previous games, his shot selection is 5% from the right baseline (Spot 1), 15% from the right elbow (Spot 2), 20% from the top of the key (Spot 3), 25% from the left elbow (Spot 4) and 35% from the left baseline (Spot 5). In this drill, a shooting spot can be selected once, multiple times, or not at all. This drill illustrates a random experiment with distribution. To help Piel decide, below is the partial table for the means and standard deviations of the random variable, Y, or the number of times he shoot the ball in a shooting spot. Shooting Spot E[Y] SD[Y] Spot 1 0.2 0.4359 Spot 2 0.6 0.7141 Spot 3 0.8 0.8000 Spot 4 the mean of 1.4 by will…
- 3. At a factory that produces doorknobs, a batch of 1500 doorknobs has just been produced. To check the quality of the doorknobs, a random sample of 100 doorknobs is selected to test for defects. Out of these 100 doorknobs, 2 were found to be defective. Based on these results, what is the best estimate you can give for the number of defective doorknobs in the batch of 1500?
