The mean of a dataset is the average of the dataset.
- The mean is 1.5
- The standard deviation is 1.58
- The median remains unchanged, the mean increases, and the standard deviation decreases when <em>5 is increased to a larger value</em>
The given parameters are:

<u>(a) Mean and Standard deviation</u>
The mean of the dataset is calculated using:

So, we have:



Hence, the mean is 1.5
The standard deviation is calculated using:

So, we have:




Hence, the standard deviation is 1.58
<u />
<u>(b) When 5 is increased to a larger value</u>
When 5 is increased:
- The median remains unchanged
- The mean increases
- The standard deviation decreases

true i think i hope its correct dont want you to get it incorrect brainliest plz
Since the equation is in y = mx+b form you can easily determine the y intercept based on the b value present.
Y = mx + b
Y = 2x - 3
B = y intercept = (0,-3).
