Hence,
95% confidence interval is BETTER than 90% confidence interval
Step-by-step explanation:
95% Confidence Interval means that in the given data set, 95% of the time (after repeated sample experiments), the data set contains the population mean. 90% confidence interval means that 90% of the time, the data set contain the mean.
Therefore a 95% confidence interval gives a higher fidelity/precision with the data statistics than 90% confidence interval.
Answer:
w^4
Step-by-step explanation:
Answer:
1) 35+5w=110
2) the starting heart rate is 73 beats per minute
3)B
4) 6mins
Step-by-step explanation:
1) since she deposits 5 dollars each week we can multiply 5 and w to find out how much money hes depositing after all the weeks are done. We need to add that with 35 to get the TOTAL money in the bank account.
2) 73 is the y intercept. The y intercept is the number when "x" is 0. So when hes just starting out/not excersizing his heart beats 73 beats per min.
3) we know that 10% of her tips is given back to her hence x(number of tips) is multiplied by 0.1, and added to 50 to find the total amount of money she receives
4) 6 mins for 1 order
