using the data provided in the dot plot above, find the mean daily low temperature. round your answer to the…

Explanation:

Step1: Count data - points

There are 2 + 1+ 1+ 2+ 1+ 3+ 1+ 3+ 1 = 15 data - points.

Step2: Calculate sum of data

[16\times2 + 22\times1+26\times1 + 28\times2+30\times3+32\times1+34\times3+36\times1] [=32 + 22+26 + 56+90+32+102+36] [=(32 + 22)+26+(56 + 90)+32+(102 + 36)] [=54+26 + 146+32+138] [=(54 + 26)+146+32+138] [=80+146+32+138] [=(80 + 146)+32+138] [=226+32+138] [=(226 + 32)+138] [=258+138] [=396]

Step3: Calculate the mean

The mean $\bar{x}=\frac{\text{Sum of data}}{\text{Number of data - points}}=\frac{396}{15}=26.4$

Answer:

26.4
