Start off calculating the total of the dog food Mimi and Honey eat together every day. Knowing 1/2 and 2/4 is the same it might help while adding up those numbers. That means they eat 3/4 + 2/4 = 1 1/4 can everyday. Multiply that by the total days, in this case 60, gives you 75 cans. You can only buy a 3-pack so dividing it by 3 gives you the total of packs she has to buy. That is in this case 25 packs. While every pack costs you $5 that means 25 packs will cost Chanel 25 x $5 = $125. Doing the same but for 29, 30 and 31 days instead of 60 should give you the answer to the last few questions.
Answer: The p-value is 0.154.
Step-by-step explanation:
Since we have given that
We claim that
Null hypothesis :
Alternate hypothesis :
Population mean = 20 hours
Sample mean = 18.5 hours
Sample standard deviation = 4.3 hours
Sample size n = 35
So, test statistic would be
So, the p value would be 0.154.
Hence, the p-value is 0.154.
