Hey guys so I have a question. How do you determine the appropriate center of measure? I know that you have to find the mean med

ian and mode but once you find the mean median and mode, how do you determine the center of measure? I'm confused.​

Answer:

The two most widely used measures of the “center” of the data are the mean (average) and the median. To calculate the mean weight of 50 people, add the 50 weights together and divide by 50 . To find the median weight of the 50 people, order the data and find the number that splits the data into two equal parts.

A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 419 gram setting. It
Pachacha [2.7K]

Answer:

We reject the null hypothesis, and accept the alternative hypothesis.

So, it means that the machine is under filling the bags

Step-by-step explanation:

Given

Null Hypothesis

H_0:\mu = 419 --- works correctly at 419g

Alternate Hypothesis

H_0:\mu < 419 --- under fills the bag

n =15 --- the sample

\bar x = 409 --- the mean

\sigma = 22 --- the standard deviation

\alpha = 0.05 --- the significance level

Required

What is the decision rule

Since n is less than 30, we make use of t test

t = \frac{\bar x - \mu}{\sigma/\sqrt n}

t = \frac{409 - 419}{22/\sqrt{15}}

t = \frac{-10}{22/ 3.87}

t = \frac{-10}{5.58}

t = -1.792

Calculate df

df = n-1

df = 15-1

df = 14

Calculate the p value from the Student's t-distribution  at df = 14 and t = -1.792

p =0.047  

Given that: \alpha = 0.05

Since p < \alpha

So, it means that the machine is under filling the bags
