Answer:
0.9955
Step-by-step explanation:
Given :
Mean weight increase , μ = 14
Sample mean weight increase , xbar = 16.3
Standard deviation, s = 5.9
Sample size, n = 45
Hypothesis :
H0 : μ = 14
H1 : μ > 14
The test statistic : (xbar - μ) ÷ (s/sqrt(n))
Test statistic = (16.3 - 14) ÷ (5.9/sqrt(45))
Test statistic = 2.3 / 0.8795200
Test statistic = 2.615
The Pvalue :
P(Z < 2.615) = 0.99554
Hence, pvalue = 0.9955 (4 decimal places).
800×8= 6400
79×8=632
add then u get ur answer
Slope: 2
y intercept: 5
rate of change : 2/1
Answer:
A
Step-by-step explanation:
Answer:
9%
Step-by-step explanation:
71 - 65 = 6 (final value - initial value)
6 / 65 = 0.0923... (divide the answer by the initial value)
0.0923 * 100 = 9.23% (Multiply by 100 to find the percentage)
Round 9.23 to the nearest whole number → 9%
