Answer:
Test statistic = - 3.354
We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.
Step-by-step explanation:
H0 : μ = 3
H1 : μ < 3
The test statistic = (xbar - μ) / (s/ √n)
Xbar = 1.50
μ = 3
s = 3
n = 45
Test statistic = (1.5 - 3) / (3/ √45)
Test statistic = - 1.5 / 0.4472135
Test statistic = - 3.354
Pvalue, using the Pvalue from Z score calculator :
Pvalue = 0.00039826
α = 0.05
Pvalue < α ; We reject H0 and conclude that the growth rate of the new shrub is less than 3cm per week.
99.99 - 64.25= 35.74
35.74/64.25= 0.556=55.6% or 56% rounded
I honestly dont know what to solve?
OK i have to go rn but u can add me on discord and i will answer it later

Use a variable for the unknown number so it would be 77-2x also if you don't know a number and a variable together means to multiply them
