Answer:
Step-by-step explanation:
From the given information;
The null and alternative hypothesis is:
sample mean x = -2
population mean = 0
SD = 6
sample size n = 25
Using t-test statistics:
t = -1.667
P-value = P(t ≤ -1.667) + P(t ≥ 1.667)
P-value = 0.1086
Since P-value is greater than , we fail to reject .
Answer:
The correct option is D) 34%.
Step-by-step explanation:
Consider the provided information.
If it is given that you scored in the 66th percentile, that means you scored "as well as or better than" 66% of the group.
Here it is given that 66th percentile that means 66% of the data located below the 66th percentile.
That means 100%-66% = 34% of the data located above the 66th percentile,
Thus, the approximately 34% percentage of apple diameters is greater than the 66th percentile.
Therefore, the correct option is D) 34%.
Answer:C. 2x2 + 3x − 1 is quadratic
Step-by-step explanation:
Quadratic expressions are polynomial expressions in which the highest power of the variable is 2.
Looking at option A, the highest power of the variable in the polynomial is 4. Therefore, it is not a quadratic expression.
Looking at option B, the highest power of the variable in the polynomial is 3. Therefore, it is not a quadratic expression.
Looking at option C, the highest power of the variable in the polynomial is 2. Therefore, it is a quadratic expression.
Looking at option D, the highest power of the variable in the polynomial is 1. Therefore, it is not a quadratic expression.
