6/8 chance should be the answer :)
Hopes this helps, and plz mark Brainliest if correct!!
The error occurred in step 2. You have to use the distributive property for the parenthesis. It is supposed to be 5p+15.
The correct solution is p>-13.
The cube root of -27 is -3
3√-27 = -3
You can check this by plugging your answer back it
X= -3
-3^3 = -27
Answer:
p value = 0.039
t = - 2.169
Step-by-step explanation:
Applying the null and alternate hypothesis
using excel worksheet to calculate for ( t and p )
t = -2.169
p = 0.039
from the results obtained
The conclusion is affected by the significance level because : 0.1 < p > 0.01
so when the significance level is = 0.1 the Null hypothesis is rejected and we can say the mean time interval will change while
if the significance level = 0.01 the Null hypothesis is accepted and we can not say the mean time interval has changed because the p -value is greater than 0.01
attached is the excel solution
