Answer:
1. y =6 2. y=4+2x
Step-by-step explanation:
Y=8x+5 would be the equation since every year,x represents year, it would be time by 8 and add 5 since that the original height it started.
Actually in this case we will make use of the z test
statistic. In which we calculate for the z score and then use the standard
normal distribution tables to find for the P value at the calculate z score.
z = (x – u) / s
z = (97 – 98) / 2
z = -0.5
The z value should be greater than 1.65 to for the null
hypothesis to be accepted. Hence rejected.
