I'm pretty sure it's 80% because 10% of 250 is 25!
20% 50
30% 75
40% 100
50% 125
60% 150
70% 175
80% 200!
90% 225
100% 250!
So the answer is 80%! Hope this helped!
Answer:
F.) H0:μ=4.55, Ha:μ≠4.55
A.) H0:μ=115, Ha:μ<115
H0:μ=69 , Ha:μ>69
Step-by-step explanation:
The null and alternative hypothesis are used in hypothesis testing.
Generally, both hypothesis negatives each other, with the alternative being the opposite of the null hypothesis.
1)the mean value of the population is 4.55 ; the researcher aims to test if the mean value differs from thus value, hence, Alternative ; μ ≠ 4.55
2.) The mean resting heart rate is said to be 115 ; this is the null claim. The reaesrch aims to test if heart rate slows down with age. Hence, the alternative will be to show that mean rate lesser Than 115 as claimed (μ < 115)
3.) Theean height of the population is claimed to be 69. Researcher aims to test if some people within the population have mean height abive this said height. (μ > 69)

Answer:
Let us assume that √2 is a rational number.
So it can be expressed in the form p/q where p, q are co-prime integers and q≠0
√2 = p/q
Here p and q are coprime numbers and q ≠ 0
Step-by-step explanation:
√2 = p/q
On squaring both the sides we get,
=>2 = (p/q)2
=> 2q2 = p2……………………………..(1)
p2/2 = q2
So 2 divides p and p is a multiple of 2.
⇒ p = 2m
⇒ p² = 4m² ………………………………..(2)
From equations (1) and (2), we get,
2q² = 4m²
⇒ q² = 2m²
⇒ q² is a multiple of 2
⇒ q is a multiple of 2
Hence, p, q have a common factor 2. This contradicts our assumption that they are co-primes. Therefore, p/q is not a rational number
√2 is an irrational number.
