A random sample of 10 subjects have weights with, №17886549, 07.04.2021 12:53

Step-by-step explanation:

We are given that

Standard deviation, s=11.0995 kg

Sample size, n=10

We have to find the variance of their weights.

We know that

Variance=A random sample of 10 subjects have weights with, №17886549, 07.04.2021 12:53

Using the formula

The variance of their weights

=A random sample of 10 subjects have weights with, №17886549, 07.04.2021 12:53

=A random sample of 10 subjects have weights with, №17886549, 07.04.2021 12:53

Hence, the variance of their weights=A random sample of 10 subjects have weights with, №17886549, 07.04.2021 12:53

Step-by-step answer
P Answered by PhD

123.19890025 kg^2

Step-by-step explanation:

We are given that

Standard deviation, s=11.0995 kg

Sample size, n=10

We have to find the variance of their weights.

We know that

Variance=(standard\;deviation)^2

Using the formula

The variance of their weights

=(11.0995)^2

=123.19890025 kg^2

Hence, the variance of their weights=123.19890025 kg^2

1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram

Step-by-step answer
P Answered by PhD

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg
