In order to find out the amount of pounds of tomatoes purchased:
- We have to know how much one pound is ($3.22 per pound)
- Total Nico spent ÷ Price per pound
So it would be
- 5.76 ÷ 3.22 = 1.78881987578
Rounding our decimal number:
- If we round to our nearest tenths it would now be 1.8
Answer:
Therefore, the total number of pounds Nico purchased for $5.76 is 1.8lb.
Step-by-step explanation:
How much test is she doing?
I think the question is missing something.
Answer:
(c) H0 should be rejected
Step-by-step explanation:
Null hypothesis (H0): population mean is equal to 5
Alternate hypothesis (Ha): population mean is greater than 5
Z = (sample mean - population mean) ÷ (sd/√n)
sample mean = 5.3, population mean = 5, sd = 1, n = 500
Z = (5.3 - 5) ÷ (1/√500) = 0.3 ÷ 0.045 = 6.67
Using the normal distribution table, for a one tailed test at 0.01 significance level, the critical value is 2.326
Conclusion:
Since 6.67 is greater than 2.326, reject the null hypothesis (H0)
