Using the Central Limit Theorem, it is found that:
- The standard deviation is
.
<h3>Central Limit Theorem</h3>
- It states that for a <u>proportion p in a sample of size n</u>, the sampling distribution of sample proportions has mean
and standard deviation 
- When two variables are subtracted, the mean is the subtraction of the means, while the standard deviation is the square root of the sum of the variances.
In 2006, 95% of new cars in the US came with a spare tire, with a sample of 250, hence:

In 2017, 72% of new cars in the US came with a spare tire, with a sample of 250, hence:

Hence, for the distribution of differences:

Ok, so the first thing you need is how much taller the second model is than the first model the way we do that is we take the second model height and divide that by the first model height 120/1.8=66.667 or 66 2/3 Second now we need to multiply the length of the middle finger by 66.667
6*66.667=400 cm now we just need to convert 400 cm to meters and since there are 100 cm in a meter we can do this 400/100=4 me so the answer is the little finger needs to be 4 meters long.
Answer: 1.
Yes , the data franchise owner is collecting, will be helpful in order to counter the criticism from the critic. As he has a record for every delivery they are making on daily basis.
2.
The scenario is that for every fifth customer , the owner cross the four lines he makes. Thus a pack of five and easy to remember. As the data on regular week days is less, As can do the same for the third customer. Crossing the 2 lines for 3rd customer.
3.
With this provision of crossing the third customer, the owner can have a better check on the late delivery. As it will bring in his notice earlier as compared to fifth crossing.
4.
With the data as provided in the table, we can come to the conclusion that on weekends , i.e. both on time delivery and late deliveries are high in numbers. It must be because of high demand on that days. So owner must make some provision like hiring some more delivery boys for weekend in order to reduce the late deliveries.
Step-by-step explanation:
2/5 i believe
because a coin has two sides ( heads or tails) then the spinner is 5 equal sections so 2/5 <3
hope it helps
