pickupchik [31]

The software output implies that the researcher is 95 percent confident that the interval given regarding the beats per minute contains the true mean heart of the adults.

From the complete information, the margin of error will be calculated as:

= (Upper limit - Lower limit) / 2

where,

Upper limit = 73.325706

Lower limit = 68.509306

= (73.325706 - 68.509306) / 2

= 4.8164 / 2

= 2.4082

Also, it should be noted that in a situation where there is an increase in the confidence interval, this will lead to an increase in the margin of error.
