# Question: q1 sally survey 100 people who travelled to curtin campus...

###### Question details

q1

Sally survey 100 people who travelled to Curtin campus by a car about how many people shared that car ride. Thousands of people travel to Curtin by a car each day.

Sally could conduct that survey with 100 people arriving by a card many times and each time survey a completely d or otially different group of people.Each time she conducts this survey with 100 people, slightly different. The mean for very possible group of 100 could be calculated, the statistics relating to all of these possible means are referred to as:

-confidence interval - range

- sample size- hypothesis

-standard deviation -estimation -centre limit theorem

-sampling distribution -population size

-point estimate - standard error and - Bessel correction

NOTE: choose the best term that describe the situation.

q2

Ming plants a few packets of impatients(flowers) seeds and records how many days it take each sprout to appear.

results:

skewness: -0.16

kurtosis: -0.52

-the point or x or line is between 15 to 25plus.

use this information you conduct an analysis to determine if mings data set on the sprout of seeds approximates a normal distribution or not.

Use 6 lines of text to complete you answer. Abbreviate normal distribution to ND to be brief. Sticky with key words and focus on your response.
