Answer:
w=-1.16u
Step-by-step explanation:
first you want to put the W's on one side and the U's on the other. we can do this by subtracting 4u from the left side and the right side making the equations 8w=-7u+2w.
next we want to subtract 2w from both sides making the equation 6w=-7u then we divide by 6 to get w=-1.16u
Answer:
B. The p-value should be higher than 0.05
Step-by-step explanation:
p-value is smaller than 0.05 means that there is significant difference in mean bicep curls made with right hand and left hand.
Since 95% confidence interval for the true mean difference is given as (-9.242, 0.2472), and confidence interval includes the value 0, we cannot say that there is significant difference. Therefore p-value is not smaller than 0.05, it is higher than 0.05.
