Null Hypothesis, H_{0}: The heart transplant operation had no impact on the patient's survival rates. Alternative Hypothesis, H_{A}: It was asserted that recipients of heart transplants had a higher chance of surviving than recipients of organs from other donors.

The large distribution from binomial, Poisson, etc. is approximated by the normal distribution. Furthermore, the variables are discrete and few, and we are working with counted data rather than real observations. Chi-square distribution should be used in the current scenario. We can determine if the two groups are the same or different by using the chi-square test. As a result, a confidence interval cannot be created.

In other words, the Null Hypothesis is true if the average for the two groups (control and treatment) is equal. In the alternative theory, The averages for the two groups (control and treatment) are different.

The simple interest formula is A = P(1 + rt) in which A is the total of money after interest, P is your principal (starting) amount, r is the interest rate, and t is the amount of time. 
For 1), plug in your variables to get  A = 1500(1 + (7/100*1.5)). Simplify, and you'll get A = 1500*1.105, and finally your answer, $1,657.50.

<span>For 2), add your interest and principal amount, then plug in your variables to get 676 = 520(1 + 5r). Distribute to get 676 = 520 + 2600r. Subtract 520 from 676 to get 156 = 2600r, then divide both sides by 2600 to get a rate of 0.06, or 6%. 

For 3), add your interest and principal amount, then plug in your variables to get 1599 = 1300(1 + 5.75t). Distribute to get 1599 = 1300 + 7475t. Subtract 1300 from both sides to get 299 = 7475t, and then divide both sides by 7475 to get .04 = t, or a time period of four years. 

The other two problems can be solved using the formula and steps described above. If you still need help with them, leave a comment and I will solve those as well. </span>

Pleaseeeeeee help meeeeeeee A boat travels for 4 hours at a constant speed of 35.25 km/h.
Fittoniya [83]

Answer:

141 km

Step-by-step explanation:

This is because as the boat travels at a constant speed, it will travel the same distance each hour.  The boat travels at 35.25 km/h, so you must multiply this number by 4.

This gets the answer 141 km.
