Question

he upper boundaries for a distribution of waiting times (in seconds) in a grocery store aisle are 49, 60, 71, and 82. List the value for each lower boundary in this distribution.

Answer 1

he upper boundaries for a distribution of waiting times (in seconds) in a grocery store aisle are 49, 60, 71, and 82.

here, it is a continuous distribution as , time is a continuous variable.

the difference between two upper bound 82 and 71 is (82-71) = 11

similarly the difference between all the upper bounds are 11.

	lower boundary of this distribution
lower boundary of the class having upper boundary 49	(49-11) = 38	the class will look like 38 - 49
lower boundary of the class having upper boundary 60	(60-11) = 49	the class will look like 49 - 60
lower boundary of the class having upper boundary 71	(71-11) = 60	the class will look like 60 - 71
lower boundary of the class having upper boundary 82	(82-11) = 71	the class will look like 71 - 82

here as this is a continuous data lower class boundary of next class = upper class boundary of previous class.
