This problem has been solved! See the answer Accuracy and Precision For the following, determine whether the information is accurate, precise, both or neither. 1. During gym class, four students decided to see if they could beat the norm of 45 sit-ups in a minute. The first student did 64 sit-ups, the second did 69, the third did 65, and the fourth did 67. 2. The average score for the 5th grade math test is 89.5. The top 5th graders took the test and scored 89, 93, 91 and 87. 3. Yesterday the temperature was 89 �F, tomorrow it�s supposed to be 88 �F and the next day it�s supposed to be 90 �F, even though the average for September is only 75 �F degrees! 4. Four friends decided to go out and play horseshoes. They took a picture of their results shown to the right: 5. A local grocery store was holding a contest to see who could most closely guess the number of pennies that they had inside a large jar. The first six people guessed the numbers 735, 209, 390, 300, 1005 and 689. The grocery clerk said the jar actually contains 568 pennies.

A:
Answer:1. Precise2.Both3.Precise5.NeitherStep-by-step explanation:Accuracy is the closeness of a measured value to a standard value.Precision is the closeness of two or more measurements to each other.1.The norm is 45 sit-ups in a minute.The students did, 64, 69,65 and 67. Values are not accurate compared to standard value 45.Values are preciseAnswer--Precise2. Average score is 89.5 Scores are 89,93,91,87 Values are precise i.e a difference of 2 from each score Values are accurate because the average score is 90 thus compared to the known average score of 89.5 they are accurate.Answer-Both 3. Yesterday temperature=89 Tomorrow=88 Next day=90 Average =75 Values are precise i.e. difference of ± 1° Values are not accurate compared to the average temperatures of 75 F Answer---Precise5. The jar contained 568 pennies The 6 people guessed the numbers as 735,209,390,300,1005, 689 The values are not precise The values are not accurate Answer---Neither
