In the final week he need to lose 1.8 kg to be able to compete as a flyweight.

<h3>Further Explanation</h3>

<u>Given:</u>

A boxer needs to lose 3\frac{1}{2} kg

In three weeks he lost 55.5 kg - 53.8 kg

<u>Question:</u>

How many kilograms must the boxer lose in the final week to be able to compete as a flyweight?

He needs to lose 3\frac{1}{2} kg, we can change it into decimal which is 3.5 kg.

Weight he lost in 3 weeks

\boxed {= 55.5 - 53.8 }\\\boxed {= 1.7 kg }\\

In the final week he needs to lose:

\boxed { = 3.5 - 1.7 }\\\boxed {= 1.8 kg }

So, in the final week the boxer needs to lose 1.8 kg

Answer:

The weight need to lose in final weeks is 1.8 kg

Step-by-step explanation:

we are given

A boxer needs to lose 3 1/2 kg in a month to be able to compete as a flyweight

so, weight need to lose

=3\frac{1}{2}kg

=3.5kg

In three weeks, he lovers his weight from 55.5 kg to 53.8 kg

so, lost weight is

=55.5-53.8kg

=1.7kg

So,

weight need to lose in final weeks = (weight need to lose)-( lost weight)

we can plug values

and we get

weight need to lose in final weeks is

=3.5-1.7

=1.8kg

A student group claims that first-year students at a university must study 2.5 hours (150 minutes) per night during the school w
AlekseyPX

Answer:

We have strong evidence that on average, students study less than 150 minutes per night during the school week

Step-by-step explanation:

Normal distribution:

mean     μ₀ = 150

Sample:

Sample size    n = 272

Sample mean   x = 141

Sample standard deviation  s  = 66

The standard error of the sample mean  SE = σ /√n

SE = 66/√272

SE = 66 / 16,49

SE = 4

Test Hypothesis:

Null hypothesis                            H₀             x  =   μ₀

Alternative hypothesis                Hₐ            x <    μ₀

z(s)  test statistics is:

z(s)  =  ( x  -  μ₀ ) / s/√n

z(s) = - 9 /4

z(s) =  -  2,25

p-value  for that z(s)      p-value  = 0,0122

Then for α =  0,05 p-value < 0,05

We are in the rejection region we need to reject H₀
