Answer:
H0 : p = 0.75
H1 : p ≠ 0.75
Step-by-step explanation:
The population proportion, P0 = 0.75 ;
Claim is that proportion of customers who use online coupons when making purchases is actually different than P0 = 0.75 (this is the calm) and the difference could be either more or less
Hence, the null hypothesis H0 : says P0 is 0.75 ;
H0 : p = 0.75
The alternative hypothesis, negating the null hypothesis argues that the proportion is not 0.75 (the difference could be either to the right or left).
H1 : p ≠ 0.75
Step-by-step explanation:
✰
- 7 , 8 , 2 , 3 , 9 , 3 , 7
Here ,
- Frequency of 7 = 2
- Frequency of 8 = 1
- Frequency of 2 = 1
- Frequency of 3 = 2
- Frequency of 9 = 2
➺ 7 and 3 has the highest frequency i.e 2. So , Mode of the given data is 3 & 7 .

Step 1: calculate the cube roots, convert the decimal into a fraction, and calculate the cube roots again
10 + 3 square root 27/1000 - 5
Step 2: calculate the cube root
10 + 3/10 -5
Step 3: subtract the #’s
5 + 3/10
Step 4: calculate and you get
53/10
Answer: 53/10
