Answer: 4:9
Step-by-step explanation:
The complete question is provide in the attachment below.
Given, Number of females = 125
Number of males = 100
Total people = 120+100=225
Now, the ratio of males to the total number of people present = ![\dfrac{\text{Total number of males}}{\text{Total people}}](https://tex.z-dn.net/?f=%5Cdfrac%7B%5Ctext%7BTotal%20number%20of%20males%7D%7D%7B%5Ctext%7BTotal%20people%7D%7D)
![=\dfrac{100}{225}](https://tex.z-dn.net/?f=%3D%5Cdfrac%7B100%7D%7B225%7D)
Divide numerator and denominator by 25 , we get
Ratio of males to the total number of people present =
Hence, the ratio of males to the total number of people present = 4:9

Answer:
We will fail to reject the null hypothesis and conclude that there is no sufficient evidence to suggest that more than 10% of the cars from a car manufacture experience engine failures before reaching a mileage of 150,000 miles
Step-by-step explanation:
We are given;
Population proportion; p_o = 10% = 0.1
Sample proportion; p = 9/65 = 0.1385
Z-score formula for this is;
z = (p - p_o)/√(p_o(1 - p_o)/n)
z = (0.1385 - 0.1)/√(0.1(1 - 0.1)/65)
z = 0.0385/0.0372
z = 1.03
From online z-score calculator, we have; p - value = 0.1504
Our p - value is greater than the significance level of 0.1.
Thus,we will fail to reject the null hypothesis and conclude that there is no sufficient evidence to suggest that more than 10% of the cars from a car manufacture experience engine failures before reaching a mileage of 150,000 miles
