The decrease in cholesterol level after eating a certain brand of oatmeal for breakfast for one month in people with cholesterol

levels over 200 is Normally distributed, with mean (in milligrams) μ and standard deviation σ = 3. The brand advertises that eating its oatmeal for breakfast daily for one month will produce a mean decrease in cholesterol of more than 10 points for people with cholesterol levels over 200, but you believe that the mean decrease in cholesterol is actually less than advertised. To explore this, you test the hypotheses and you obtain a P-value of 0.052. Which of the following is true?

Answer:

some evidence against H0 can be seen, and a study using a larger sample size will be recommended

Step-by-step explanation:

The decrease in cholesterol level after eating a certain brand of oatmeal for breakfast for one month in people with cholesterol levels over 200 is Normally distributed, with mean (in milligrams) μ and standard deviation σ = 3. The brand advertises that eating its oatmeal for breakfast daily for one month will produce a mean decrease in cholesterol of more than 10 points for people with cholesterol levels over 200, but you believe that the mean decrease in cholesterol is actually less than advertised. To explore this, you test the hypotheses and you obtain a P-value of

going by the parameters

standard deviation is 3

mean of the sample=μ

There is some evidence against H0, and a study using a larger sample size will be essential

morpeh [17]

Answer:

2 1/6

Step-by-step explanation:

The combined amount in cups needed can be determined by adding the cups of rolled oats with the cups of raisins

1\frac{2}{3} + \frac{1}{2}

1 \frac{4 +3}{6}

= 1\frac{7}{6}

Converting the improper fraction to mixed fraction gives

1 + 1\frac{1}{6}

2\frac{1}{6}

Let x and y be any numbers at all with x ≤ y. Show that the number of integers between x and y is [y] - [x] +1.That is show that
ddd [48]

Answer:

the explanation is given below.

Step-by-step explanation:

  • Here what is applied is assumption of range of values of number from say 1 - 100
  • In total, i stopped at 100 on the dot.

from this, the lowest number is 1 and the highest number is 100

  • hence the range of the numbers = Difference between Highest and Lowest
  • range = 100 - 1 = 99, the 99 gotten as the range is indicative that a number has been missing.

  • In order to make up the 100, an integer is added to the difference = 99, i.e 99 is added to 1 to make up the 100.

  • Furthermore, if 0 is exclusively out when numbers are counted up 100 with 0 inclusive, in such case, the first and last number are excluded from the counting. as such the integers will be {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20.........., 99} since both 0 and 100 are not included.

  • Here, if we try to get the range = highest - lowest = 99 - 1 = 98, it implies that to make up the 99, an integer is added to the result of the difference = 98+1 = 99

  • As such, the number of integers between two numbers is the difference between the highest and the lowest number plus 1 i.e highest - lowest + 1 = y - x +1 = (the floor of y) - ( the ceiling of x) + 1

This is simple interest :<br> $640, 3%, 2 years<br> anyone knows how to explain?
Elena L [17]
I=PRT
Interest=I
P=principal
R=rate in decimal
T=time in years

given
asuming 640 is the principal and not the interest
P=640
R=3%=0.03
T=2


I=640*0.03*2
I=19.2*2
I=38.4

interst=$38.40
