Answer:
Step-by-step explanation:
The assumptions include:
The samples from each population must be independent of one another: this was adequately met.
The populations from which the samples are taken must be normally distributed: this was not talked about
The population standard deviations must be known: not known
or the sample sizes must be large (i.e. n1≥30 and n2≥30: true
The validity conditions for a two-sample z-test/interval were not all adequately met
Use exact numbers
Answer:
y=2x+5
Step-by-step explanation:
distribute 2 to x and 1, do this by multiplying each.
you should get y-3=2x+2.
then you have to move the -3 from the left to the right. but when you do this you have to change the -3 to a positive 3. then combine 3 and 2.
you then get the answer, y=2x+5.
