Answer:
There is enough statistical evidence to claim that the average length is not 10 cm.
Step-by-step explanation:
The claim that the average lenght is 10 cm, is the null hypothesis (has the "equal" sign). The claim that the average length is not 10 cm is the alternative hypothesis.
The significance level is assumed to be 0.10.
The sample mean is 7 cm and the sample standard deviation is 1 cm.
The degrees of freedom are
The t-statistic is:
The P-value of t=-30 is P=0.
This means there is almost no chance of getting this sample if the mean is really 10 cm.
There is enough statistical evidence to claim that the average length is not 10 cm.
Answer:
D. (y-2) becomes (y-5) and -5 < -2
Step-by-step explanation:
When transforming functions, the following applies:
• Adding/subtracting inside the parenthesis to the input shifts the function left(+) and right(-).
• Adding/subtracting outside the parenthesis to the output shifts the function up(+) and down(-).
• Multiplying the function by a number less than 1 compresses it towards the x-axis.
• Multiplying the function by a number greater than 1 stretches it away from the x-axis.
In this situation, the circle is shifted up 3 units and the variable y which controls this is in the function. To move it up you will subtract 3 in the parenthesis for (y-2) so it becomes (y-5). This will move the vertex 3 units higher.
