<em><u>26.45 + 2.55 = 29 . . . but with correct sig figs . . . the answer is . . . 29.00 . . . i.e. [4] sig figs</u></em>

 . . . why? . . . because even though 26.45 has [4] sig figs & 2.55 has [3] sig figs, the number of sig figs to the right of the decimal are the critical sig figs . . . and there are [2] sig figs to the right of the decimal, so the answer/result can also beas precise as having [2] sig figs to the right of the decimal as well.

A sample of men's heights was taken and the mean was 68.8 inches. The standard deviation is 2.8 inches. What percent of the men
jarptica [38.1K]

Answer:

87.29%

Step-by-step explanation:

Given: Mean= 68.8 inches

           Standard deviation= 2.8 inches

           

Now, finding the percent of the men in the sample were greater than 72 inches.

We know, z-score= \frac{x-mean}{standard\ deviation}

z-score= \frac{72-68.8}{2.8}

⇒ z-score= \frac{3.2}{2.8} = 1.14

∴ z-score= 1.14

Next, using normal distribution table to find percentage.

Coverting 0.8729 into percentage= 0.8729\times 100

We get the percentage as 87.29%

Hence, 87.29% of the men in the sample were greater than 72 inches.
