Please consider the attached graph.
We have been given that there are two different models of the same triangular-shaped garden. The height of the model on the left is 14 cm. We are asked to find the height of the model.
First of all, we will convert 14 cm into feet.
We can see that model on left side has a scale of 1 cm is equal to 15 feet.
14 cm = 14×15 feet = 210 feet.
We can see that model on the right side has a scale of 1 cm is equal to 7.5 feet.
Since both models represent same triangular-shaped garden, so the actual height for the both models will be same.
Now we need to convert actual height of 210 feet into inches using 2nd scale.
Therefore, the height of the model on right is 28 inches.
Answer:

b
Step-by-step explanation:
From the question we are told that
The number of bootstrap samples is n = 1000
From the question we are told the confidence level is 95% , hence the level of significance is
=>
Generally the percentage of values that must be chopped off from each tail for a 95% confidence interval is mathematically evaluated as
=>
Generally the number of the bootstrap sample that must be chopped off to produce a 95% confidence interval is
=>
=>
Answer: a) 0.5636 b) 0.7881
Step-by-step explanation:
We assume that women’s heights are normally distributed .
Let x be the random variable that represents the shoe sizes.
Also, The population mean = ; Standard deviation:
a) Formula for z:-
Put x= 64, we get
Now, the probability that the male shoe sizes are greater than 8 :-
Hence, the probability that her height is less than 64 inches = 0.5636
b. Sample size : n= 25
Then , the formula for z :-
Put x= 64, we get
Then, the probability that they have a mean height less than 64 inches.:_
Hence, the probability that they have a mean height less than 64 inches. =0.7881
