Please don't provide handwritten solution ..... A sample of 20 plants was collected and the mean height was calculated as 8.3 cm. A 95% confidenceinterval for the true mean height of plants of that particular species is (3.5 cm, 13.1 cm).Four students gave the following interpretations of the confidence interval. Which of the following iscorrect?We can be fairly confident that 95% of all plants of that species have a height between 3.5 cm and 13.1 cm.We are 95% confident that the true mean height is 8.3 cm since that value lies in the confidence interval.The probability is 0.95 that the mean height lies in the interval (3.5, 13.1)None of the above

3.) Mr. Richards and Mr. Dolge each began improving their yards over the summer by buying bags of soil (fancy dirt) and bags of mulch (bark dust). Since Mr. Dolge has access to a truck, Mr. Richards got a ride and as a result they got their supplies from the same store. Mr. Dolge spent $97 on 3 bags of soil and 14 bags of mulch. Mr. Richards got 14 bags of soil and 7 bags of mulch for $161. They forgot to get a receipt, but just in case they need more supplies, they are wondering how much each bag of soil will cost, and how much each bag of mulch will cost. What should they find these prices to be?

2. Jimmy was drawing rectangles at his desk. After a while he concluded that if you increased one of the sides by 10% and decrease the other side by 10% the area won't change. Is Jimmy correct? Provide a formal mathematical argument as well as a "teacher response" to Jimmy.
A contractor has a contract which which will expire in 40 days. At present, he has 80 men on the job and can finish the job in 50 days. The wage per day of 40 men is $500 each and the other 40 men is $300, each for 8 hours work per day.

If any, how much is the savings? No overtime work is permitted.

The officers of a high school senior class are planning to rent buses and vans for a class trip. Each bus can transport 72 students, requires 5 chaperones, and costs $1,400 to rent. Each van can transport 8 students, requires 1 chaperone, and costs $120 to rent. Since there are 432 students in the senior class that may be eligible to go on the trip, the officers must plan to accommodate at least 432 students. Since only 50 parents have volunteered to serve as chaperones, the officers must plan to use at most 50 chaperones. How many vehicles of each type should the officers rent in order to minimize the transportation costs? What are the minimal transportation costs? The officers should rent buses and The minimal transportation costs are $ vans to minimize the transportation costs.
