A farmer would like to estimate the mean amount of milk produced per day by his 300 cows. He selects a

random sample of 15 cows and records the amount of

milk produced in gallons) by those cows. The dotplot

shows the data. Given that all of the recorded values are integers, what is the value of the standard error of the mean?

0.765

0.792

2.267

2.346

0.765

Step-by-step explanation:

The dot plot shows the data

x= 20,21,22,23,24,24,25,25,25,26,26,27,28,29,31

The mean x`= ∑x/n =20+21,+22,+23,+24,+24,+25,+25,+25+,26+,26+,27+,28+,29+,31/15= 376/15

=25.067

where n is the sample size= 15

The standard deviation is σ=2.96

( using calculator)

The standard error is calculated as

SE= σ/√n

SE= 2.96/√15

SE= 0.765

this doesn't make sense lol

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
