Question

Section 6! Suppose you are conducting an Experiment to Egtimate the average height of Students in a School. You randomly Select 100 Students and measure their height. a) If the student's height are distributed with a mean of 170cm and a Standard deviation of 10cm, use the Central limit theorem to determine the probability that the random Sample mean height of 100 students is between 168 cm and 172cm. (Use standard normal distribution table wherever required). b) Suppose the population mean Height of students is unknown, but the Standard deviation is known to be 10cm. The Sample of 100 students has a mean height of 169.5cm. Calculate a 95% Confidence interval for the population mean height of the Student based on this Sample mean height of 100 Students.

          Section 6!
Suppose you are conducting an Experiment to Egtimate
the average height of Students in a School. You randomly
Select 100 Students and measure their height.
a) If the student's height are distributed with a mean
of 170cm and a Standard deviation of 10cm, use
the Central limit theorem to determine the probability
that the random Sample mean height of 100 students
is between 168 cm and 172cm. (Use standard normal
distribution table wherever required).
b) Suppose the population mean Height of students is
unknown, but the Standard deviation is known
to be 10cm. The Sample of 100 students has a
mean height of 169.5cm. Calculate a 95% Confidence
interval for the population mean height of the
Student based on this Sample mean height of
100 Students.
