Astudent wondered if more than 10% of students enrolled in an introductory chemistry class dropped before the midterm. suppose he performed a hypothesis test to test his claim. in the context of the problem, what would happen if the student made a type i error?

The test result would accept the alternate hypothesis stating that 'More than 10% of the students enrolled in an introductory Chemistry class dropped before the midterm'.

Explanation:

In this case, the null and alternate hypothesis would be:

Null Hypothesis: Less than or equal to 10% of the students enrolled in an introductory Chemistry class dropped before the midterm.

Alternate Hypothesis: More than 10% of the students enrolled in an introductory Chemistry class dropped before the midterm.

A Type I error is when a true null hypothesis is rejected by mistake or due to an error. This means that it is true that 'Less than or equal to 10% of the students enrolled in an introductory Chemistry class dropped before the midterm' but this is rejected due to an error or mistake. Hence, the alternate hypothesis will be found as the result of the test due to the error.

the correct answer is 2.

a slump in geology means a mass movement process of slope failure. a mass of rock or unconsolidated material drops along a slip surface. in other words, rock layers move a short distance down the slope. the slump block is an intact block (2), without any landslide material.

in this image, 1 is the surface of rapture (scarp), 2 the slump block, 3 main scarp (crown), 4 base of rapture with debris flow.

slumps are caused by clear cutting on unstable soils and the sagging of earth, in coastal areas they are due to wave infiltration.

uses : -

1.aneroid barometers primarily measure whether pressure is rising or falling.

2.aneroid barometers are often used for reading pressure in homes and recreational boats.  

3.other uses may include barographs in meteorology and altimeters in modern aircraft.  

4.this type of barometer can announce whether a high or low pressure system is coming or whether it is becoming more intense.  

5.there are different types of aneroid barometers, such as the altimeter, which measures altitude, or distance above sea level.  

6.another example is a barograph, which is a modified aneroid barometer that provides constant readings of atmospheric pressure on graph paper.  

7.when used in this capacity, the aneroid barometer can store a week's worth of data.

android diameter a device for measuring atmospheric pressure , often specially calibrated for use as an altimeter ,consisting of a box or chamber partially exhaused of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air
