The manufacturer claims that your new car gets 27 mpg on the highway. You suspect that the mpg is more than 27 for your car. The 34 trips on the highway that you took averaged 28 mpg and the standard deviation for these 34 trips was 6 mpg. What can be concluded at the 0.10 level of significance?

Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

H0: = 27
Ha: [ Select ] [">", "Not Equal To", "<"] 27
Test statistic: [ Select ]["Z", "T"]
p-Value =[ Select ] ["0.04", "0.34", "0.17", "0.08"]
[ Select ] ["Reject Ho", "Fail to Reject Ho"]
Conclusion: There is [ Select ] ["statistically significant", "insufficient"]evidence to make the conclusion that the population mean mpg for your car on the highway is greater than 27.
p-Value Interpretation: If the mean highway mpg for your car is equal to [ Select ] ["27", "30", "28", "29"] and if another study was done with a new randomly selected collection of 34 trips, then there is a [ Select ] ["17", "34", "4", "8"] percent chance that the average highway mpg for this new sample would be greater than [ Select ] ["28", "29", "27", "30"] .
Level of significance interpretation: If the mean highway mpg for your car is equal to [ Select ] ["27", "28", "30", "29"] and if a new study was done with a new randomly selected collection of 34 highway trips then there would be a [ Select ] ["10", "24", "5", "17"] percent chance that this new study would result in the false conclusion that the mean highway mpg is greater than 27.
