Answer:
(b) It means that the results that Tessa obtained are too unusual to be explained by chance alone
Step-by-step explanation:
The test for statistical significance is a comparison of the result to the probability that it occurred by chance. The probability of a chance occurrence is usually set at 1% or 5%. The lower the percentage, the less likely a chance occurrence is, and the more difficult showing statistical significance becomes.
Answer:
0.00259
Step-by-step explanation:
Probability, p of making the correct guess ; 1 / 5 = 0.2
Passing grade = 50% ; 50% * 20 = 0.5 * 20 = 10
q = probability of not passing ;
q = 1 - p = 1 - 0.2 = 0.8
Using the binomial distribution formula :
P(x >=x) = nCx * p^x * (1 - p)^(n - x)
P(x >= 10) = p(x = 10) + p(x = 11)+... + p(x = 20)
P(x >= 10) = 10C20 * 0.2^10 * 0.8^10
P(x >=) 0.00259
Answer:
Table 4th is showing the function that is decreasing only over the interval
Step-by-step explanation:
We have been given four tables below:
To determine the function that is decreasing only in the given interval
We will check the values after -1 in all four tables
The table in which values is only decreasing after -1 will be the table which shows a function is decreasing only.
In table 1 the value of x is increasing
In table 2 and 3 the value is increasing and then decreasing but we will consider only decreasing case
Therefore, Table 4th is correct.
Answer:
The answer is the family size
Step-by-step explanation:
I had to find how much it is per ounce and for the small box it cost $1.25 per ounce and for the family size it cost $0.41 which is less than $1.25 so the answer would be the family size of Honey Nut Cheerios
