Find and interpret the standard deviation of each set of data. {145, 166, 171, 150, 188}

15.2; Since the standard deviation is large compared to the mean of 164, the data are relatively spread out.

15.2; Since the standard deviation is small compared to the mean of 164, the data are relatively close to the mean.

15.40; Since the standard deviation is large compared to the mean of 164, the data are relatively spread out.

15.40; Since the standard deviation is small compared to the mean of 164, the data are relatively close to the mean.

step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
