beth volunteered to help with belltowns annual spring scavenger hunt. she gave each kid a list of 10 items. after an hour, she recorded how many items each kid had found. belltowns scavenger hunt complete the sentences. the mean of the data is _ items. it describes the ______ of the distribution. 6 ... center 6 ... spread 7 ... center 7 ... spread

Answer

Answer:

7 ... center

Explanation:

Step1: Count data - points

There is 1 '4', 2 '5's, 3 '6's, 7 '7's, 4 '8's, 1 '9', 1 '10'.

Step2: Calculate sum of data

[4\times1 + 5\times2+6\times3 + 7\times7+8\times4+9\times1+10\times1=4 + 10+18+49+32+9+10 = 132]

Step3: Calculate number of data - points

[1 + 2+3+7+4+1+1=19]

Step4: Calculate the mean

(\text{Mean}=\frac{132}{19}\approx 6.95\approx7) The mean describes the center of a distribution.
