Answer:
Step-by-step explanation:
From the given information:
The null and the alternative hypothesis can be well written as:


Given that:
n = 200
x = 135
Alpha ∝ = 0.05 level of significance
Then;
⇒ 
= 200 × 0.6 × (1 -0.6)
= 200 × 0.6 × 0.4
= 48 ≥ 10
The sample proportion 

= 0.675
The test statistics 


Z = 2.165
The P-value = P(Z > 2.165)
= 1 - P(Z < 2.165)
From the z tables
= 1 - 0.9848
= 0.0152
Reject the null hypothesis since P-Value is lesser than alpha. ( i.e. 0.0152 < 0.05).
Thus, there is enough evidence to conclude that the value of the population proportion is greater than 0.6
Answer:
The histogram that represents the correct frequency of each class interval in the given data set, is: histogram B.
What is a Histogram?
A histogram is a type of bar graph that uses bins to represent the frequency of a class interval.
Given the data points above, the histogram in option B has the correct bars that represent the appropriate frequency of each class interval.
Therefore, the histogram that represents the data set given is Histogram B.

Answer:
A
Step-by-step explanation:
Taking the square root of both sides.
Answer:
c= -18
Step-by-step explanation:
c+4c= -90
combine like terms
5c= -90
Divide by 5 on both sides
c= -18
Hello there,
If you are putting 28 on the less than side it is.
Correct
30>28
Incorrect
28>30
Hope this helped!
