will give it my best
it's almost 3 am and it's 6 hours until exam, and i just finished answering the exam cramming questions
time to study (and hopefully sleep) now
can't believe the incredible btc prague memories i have are now almost from a year ago...
for those going for the first time
you're gonna have an absolute blast, the nightlife is like no other
any data analysts here?
have a stats problem that i'm too dumb to solve in preparation for an upcoming statistics final, excel only.
any sort of enlightenment would be much appreciated
The company intends to evaluate the effectiveness of customer service training. The average time spent per customer before the training was 14 minutes. The service manager randomly selects some employees who recently completed the training and measures the time spent per customer. Can the training be considered effective, and has it had the desired impact on the average time? Use a significance level of 5%.
a) Formulate the hypotheses.
b) Choose an appropriate test method and calculate the test statistic.
c) Formulate the null hypothesis rejection rule.
d) Draw a correct conclusion based on the hypothesis test result.
e) Could the null hypothesis also be rejected with a confidence level of 99%? Justify your answer.
The data on the time spent per customer by the selected employees are as follows:
9, 10, 7, 9, 8, 6, 12, 10, 9, 8, 12, 11, 9, 10, 9, 7, 9, 8, 10, 9, 11, 14, 8, 7, 9, 10, 7, 6
oh absolutely, it helps me leaps and bounds over the confusing parts. the ability to ask fornfurther explanations and even explain it like i was five at points definitely speeds up the process of learning
Ohh, that sounds incredibly nice and I really hope that your final went well. By the way, these are the exact topics that I've covered in my class throughout the past semester and will be having my final on tomorrow 🤗
