This question is asking which of the following statements is not true about physical development in children, and then we're given four options.
00:08
Children need a lot of movement to grow up strong and healthy.
00:11
I would say that that's certainly true.
00:13
Second, healthy physical development helps children manage their own stress.
00:17
There are studies out there that do show that.
00:19
And then the last option, practicing physical skills early in life makes it easier to continue being physically active in adulthood.
00:26
There's also a lot of evidence to back that up if you look into that.
00:29
That third option is the only one that i would think is not always true children tend to develop muscle memory naturally without any adult encouragement so in that case i would say option c is probably the correct answer to this question since this is categorized as a statistics question i would definitely encourage you to run a hypothesis test to see if there's any correlation there the one that would be probably most appropriate if we're talking about hypothesis testing for this question or maybe this topic would be what we call matched pairs test.
01:09
The other name that is associated with this kind of hypothesis test is a dependent t -test.
01:15
And basically what you would do in this example is we would look at one group of children who have had adult interaction, so one group over here one group of children with adult support and then we'd also have a group of children without group of children without adult support and then we would want to come up with some metric to measure their muscle memory so i'm not sure exactly what that would be but maybe it's you know how long they they can grasp an object in minutes or something.
01:57
So we would have all these data lists.
02:00
So maybe i had a sample size of 50 kids over here, 50 kids over here, and we have all these data values...
