The article "The Accuracy of Stated Energy Contents of Reduced-Energy, Commercially Prepared Foods" (J. of the Amer. Dietetic Assoc., 2010: 116—123) presented the accompanying data on vendor- stated gross energy and measured value (both in kcal) for 10 different supermarket convenience meals):

Meal: 1 2 3 4 5 6 7 8 9 10
Stated: 180 220 190 230 200 370 250 240 80 180
Measured: 212 319 231 306 211 431 288 265 145 228

Carry out a test of hypotheses to decide whether the true average % difference from that stated differs from zero. (Note: The article stated "Although formal statistical methods do not apply to convenience samples, standard statistical tests were employed to summarize the data for exploratory purposes and to suggest directions for future studies."]

step-by-step explanation: i just don't

25 questions , because they start with 100.  

350-100=250 .  

. 250/10=25

step-by-step explanation:

first take off 100, then what x 10 = 250? that is your answer. (25)

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
