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)

Step-by-step explanation:
Considering their concepts, on the graph of a function, the domain and the range are given as follows:
- Domain: Horizontal axis, values of x.
- Range: Vertical axis, values of y.
<h3>What are the domain and the range of a function?</h3>
- The domain of a function is the set that contains all the values of the input.
- The range of a function is the set that contains all the values of the output.
In a graph, the horizontal axis represents the input and the vertical axis represents the output, hence the domain and the range are given as follows:
- Domain: Horizontal axis, values of x.
- Range: Vertical axis, values of y.

Answer:
the number of pounds of cashews Wayne needs, if he plans to use p pounds of almonds
Step-by-step explanation:
Ration of Almonds:cashows = 1:2
Almonds/cashows = 1/2
2Almonds = cashows
f() = 2p <--> cashows = 2Almonds
As a result, the function represents the number of pounds of cashews Wayne needs, if he plans to use p pounds of almonds
