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.
Answer:
Interest Rate : 0.0346 or 3.46%
Step-by-step explanation:
• 429.2=350*(1+x)^6
• 429.2/350= (1+x)^6
•(429.2/350)^(1/6)= 1+x
•(429.2/350)^(1/6)-1= x
Check work:
350*(1+0.0346)^6=429.2
