Answer:
w=−5
Step-by-step explanation:
Answer:
a) State the random variable
Random variable : x
which refers to a randomly selected student from the college that is left-handed.
b) state population parameter
population parameter : P
which is the percentage of all students from the college that are left handed
c) state the hypotheses
The hypothesis are;
Null hypothesis H₀ : p = 0.11
Alternative hypothesis H₁ : p > 0.11
d) State the Type I error in the context of this problem.
Type - I Error: Rejecting that the % of all the students from the college that are left-handed is 11% when actually the % is really 11%
(Reject H₀ when H₀ is true)
e) State the Type 11 error in the context of this problem
Type-II Error: Failing to Reject that the % of all the students from the college that are left-handed is 11% when the % is really higher than that
(Fail to reject H₀ when H₀ is false)
Answer:
11
Step-by-step explanation:
Step 1: Parenthesis
6² - 5²
Step 2: Exponents
36 - 25
Step 3: Subtract
11
The dot is multiplication.
Answer:
yeah here I's the answer
Step-by-step explanation:
Weights of adult males are normally distributed with a mean of u = 85.5 kg and a standard deviation of o= 17.7 kg. If a sample yields x = 80 kg, how many standard deviations is this away from the mean? What is the probability that another sample of size is n=1000 has mean < 80kg? (Hint: Use the Central Limit Theorem.)
The answer is approximately 12.57
