Answer: 303 meters
Step-by-step explanation:
The Burji Khalifa is 830 meters in height and the Sears tower is 527 meters in height.
To find out how much higher the Burji Khalifa is than the Sears tower, subtract the height of the Sears tower from the height of the Burji Khalifa:
= 830 - 527
= 303 meters
Step-by-step explanation:
maybe maybe a 6% chance because it might depend on how you roll the dice maybe?
Answer:
b. We do not have enough information to make a conclusion.
Step-by-step explanation:
For testing difference of means our null hypothesis and alternative hypothesis is
H0: There is no significant difference between the average packing time of old machine and new machine i.e. μold-μnew=0.
Ha:There is significant difference between the average packing time of old machine and new machine i.e. μold-μnew≠0.
When the confidence contains the null values then there is no significant difference exists. Here the specified null value is 0. A 95% confidence interval (-6.85, 0.34) shows that it contains null value so, there is no significant difference between the average packing time of the two machines at 5% level of significance. This results is for 95% confidence interval. For 90% confidence interval result may vary and we don't have sufficient information given to compute 90% confidence interval.
