张辽过了以后,吕布确实卡的人****。虽然10塔是可以过的,但对星星要求太高,所以想先算一算,以11塔去过,是不是比升星星花的时间要短一些。
在不同的时间段,将10级将军塔,从20%提升至60%,每次的截图如下:

每次铸造石用量进行记录,然后可以列如下excel表格:
ignore_js_opimg id="aimg_3194229"src="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/3194229be7c1e974506749e3fad389b0b52ec15.jpg"style="max-width: 750px;"zoomfile="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/3194229be7c1e974506749e3fad389b0b52ec15.jpg"file="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/3194229be7c1e974506749e3fad389b0b52ec15.jpg"class="zoom"onclick="zoom(this, this.src)"onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"alt=""//ignore_js_op
光是均值,不能完全说明问题,毕竟堂哥能浮动,大家有脸白脸黑的区别。于是,我们进一步分析方差和标准差
ignore_js_opimg id="aimg_3194230"src="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/3194230fce29bd8728cee06a42176ff5b714045.jpg"style="max-width: 750px;"zoomfile="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/3194230fce29bd8728cee06a42176ff5b714045.jpg"file="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/3194230fce29bd8728cee06a42176ff5b714045.jpg"class="zoom"onclick="zoom(this, this.src)"onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"alt=""//ignore_js_op
其实excel可以公式计算,但笔者为了更好的说明过程,半手动进行了计算。
首先,计算每组的值,减去平均数
其次,把上一步的结果进行平方
再次,将上述平方值相加
然后,将平方值除以n,这里是8组,获取样本方差
终于到下一步,再开方获取标准差
有了标准差,接下来我们可以按照正态分布进行估计。(什么,有人说堂哥不是正态分布,这。。。。那当我啥都没说。只是自然界的绝大多数事件符合正态分布哦)
列示1-3倍标准差的值,加减到均值上面
ignore_js_opimg id="aimg_3194231"src="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/31942314f4280bf1a0721cb90339966c6089fd1.jpg"style="max-width: 750px;"zoomfile="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/31942314f4280bf1a0721cb90339966c6089fd1.jpg"file="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/31942314f4280bf1a0721cb90339966c6089fd1.jpg"class="zoom"onclick="zoom(this, this.src)"onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"alt=""//ignore_js_op
根据上述计算值估算铸造石用量。
根据前述计算,获得下表
ignore_js_opimg id="aimg_3194254"src="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/3194254a8f78d78e245bf118fbef2fa39130092.jpg"style="max-width: 750px;"zoomfile="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/3194254a8f78d78e245bf118fbef2fa39130092.jpg"file="https://res-bbs.aoshitang.com/data/attachment/forum/202104/25/3194254a8f78d78e245bf118fbef2fa39130092.jpg"class="zoom"onclick="zoom(this, this.src)"onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"alt=""//ignore_js_op
因为1-3倍标准差值,在正态分布中,其涵盖范围分别为68.3%,95.5%和99.7%,故我们完全可以认为,在99.7%的概率下,10塔到11塔所需的石头在148371-151962之间。所以脸白脸黑在铸造这件事情上,差异不太大,毕竟点这么多次,脸黑的成分也几乎被中和啦!
希望大家早日铸造好宝塔,快速过图哦!
