890×(1+0.187÷12)^(12)−890×(1+0.125÷12)^(12)=63.61....answer
Answer:
Step-by-step explanation:
Given that a researcher is using a repeated-measures design to test for mean differences among four treatment conditions.
The data for this study consist of 10 scores in each treatment.
We have to find the total subjects who participated in the study.
Each treatment has 10 scores
No of treatments = 4
Hence subjects participated in the study
= no of treatment x no of subjects
= 
Given :
Distance travelled , d = 180 miles.
Time taken , t = 4 hours.
To Find :
Speed in feet per minutes.
Solution :
Distance in feet is , d = 180×5280 = 950400 feet.
Time taken , t = 4×60 = 240 minutes.
Speed is given by , 

Hence, this is the required solution.
