Answer:
Delta Ft = 70*3 - 42*7 = 168 #$
3/8 2/5 0.44 0.5 is the answer d !!
We are given the parent function, f(x) = 5x and is vertically compressed by a factor of 1/2, shifted to the right (3 units) and down two units.
Vertical compression makes the function:
f(x) = (1/2) * 5x
shifted 3 units to the right makes the function:
f(x) = (1/2) * 5 (x+3)
shifted 2 units down makes the function:
f(x) = (1/2) *(5 (x+3)) - 2
therefore, this function is the resulting function after performing all three adjustments of the parent function. First, compression, then shift to left/right, then shift up and down.
Step-by-step explanation:
- The random variable (x) here would be a randomly selected student from the college that is left-handed.
- The population parameter would be 11% of America's total population. The total population as of 2019 is believed to be 328.2 million, and 11% of that figure is about 36.1 million (thirty-six million one hundred thousand).
- Hypotheses: Remember, the <u>null hypothesis</u> usually reflects the held view of the researcher, and since we are told the college wants to know if the data provide enough evidence to show that students at this college have a different percentage of left-handers than the general American population. It could read;<em> There is a statistically significant difference in the percentage of left-handers in the college than the American population. </em>While the <u>alternate hypothesis</u> could read; <em>There is </em><u><em>no</em></u><em> statistically significant difference in the percentage of left-handers in the college than the American population.</em>
- The Type I error implies rejecting the null hypothesis when it is actually true. That is: <u>Rejecting that the % of all students from that college that are left-handed is 11 % when the % is really 11 %.</u>
- The Type II error implies accepting the null hypothesis when it is actually false. That is: <u>Failing to reject that the % of all students from that college that are left-handed is 11 % when the % is actually different.</u>
