Question

collect the daily maximum temperatures recorded for a period of 30 days in your city. present this data as a grouped frequency table. Find the mean of the data using an appropriate method.​

Answer 1

Answer:

the 30 days temperature is .28,27,29,21,21,239

,19.84,17,22,23.48,24,25,25,25,28,29,30,30,30 ,30.96,32,33,33,33,34,34,32,31,33,32.

now we will find the mean of the total data

so mean = sum of observations/number of observations = 28+27+29+21+21+23+19+17+22+23.+24+25+25+25+28+29+30+30+30+30+32+33+33+33+34+34+32+31+33+32/30

= 833/30

= 806.06666667

so, the mean temperature of city is= 806.06666667
